Resources for Training Machine Learning Algorithms Using CAM6 Simple Physics Packages
User Collection- Creator:
- Limon, Garrett
- Description:
- The collection contains the code and the data used to train machine learning algorithms to emulate simplified physical parameterizations within the Community Atmosphere Model (CAM6). CAM6 is the atmospheric general circulation model (GCM) within the Community Earth System Model (CESM) framework, developed by the National Center for Atmospheric Research (NCAR). GCMs are made up of a dynamical core, responsible for the geophysical fluid flow calculations, and physical parameterization schemes, which estimate various unresolved processes. Simple physics schemes were used to train both random forests and neural networks in the interest of exploring the feasibility of machine learning techniques being used in conjunction with the dynamical core for improved efficiency of future climate and weather models. The results of the research show that various physical forcing tendencies and precipitation rates can be effectively emulated by the machine learning models.

- Description:
- The data represents weekly output from three 60-year CAM6 model runs. The output includes state (.h0. files) and tendency (.h1. files) fields for three difference model configurations of increasing complexity. State fields include temperature, surface pressure, specific humidity, among others; while tendencies include temperature tendencies, specific humidity tendencies, as well as precipitation rates. Using the state variables at a given time step, machine learning techniques can be trained to predict the following tendency field, which can then be applied to the state variables to provide the state at the next physics time step of the model.

Realm 3: Tumulus Excavations
User Collection- Creator:
- Galaty, Michael
- Description:
- The PASH Data Collection is comprised of Five data “realms”: 1) Survey and site data, 2) Settlement excavations, 3) Tumulus (burial mound) survey and excavations, 4) Artifact analysis, and 5) Geological data. All databases, field notebooks, unit and profile drawings, photographs, photo descriptions, radiocarbon dates, and geophysical survey data related to the tumuli excavations have been made available in PASH Deep Blue Data Realm 3., Total size of all files: approximately 2 gigabytes Chapter(s) linked to: Eight Abbreviations: “T” = tumulus, as in T099; “S” = site, as in S006, The excavation methods employed by PASH at tumuli replicate those employed at settlements. Natural stratigraphy was followed where possible, and arbitrary stratigraphic levels were defined when necessary. Arbitrary stratigraphic levels at tumuli often exceeded the 10 cm interval used at settlements, due to the large number of large rocks that needed to be removed. Due to the numerous rocks, not all mound fill was screened; rather, we screened every third bucket through quarter-inch mesh. By contrast, all soil from features was screened. Soil was sampled for flotation and water screening from every level and feature, but unlike samples from settlements, it has not been processed and analyzed. Each tumulus, being roughly circular, was divided into quadrants along the cardinal directions, and 1-m baulks between quadrants were defined. Quadrants were excavated separately by level. Sometimes quadrants were excavated concurrently. Tumulus unit/level/feature designations are therefore preceded by tumulus (T000) and quadrant (Q000) numbers. Artifact provenience was recorded down to levels and features, with important in situ artifacts sometimes being mapped into level/feature drawings along x-y-z axes. Strata and artifacts were measured cm below surface using a dumpy level. All levels and features were drawn and photographed, individually and by quadrant. , In each mound we followed natural stratigraphy whenever and wherever possible. However, given the steep downward curves of many strata, following the slopes of mound surfaces, this was not always possible. Thus, it is likely that some levels combine artifacts from different mound strata. To control partially for this difficulty, quadrant levels were often subdivided into separate units on the interior or the exterior of mounds (designated “collections units” or CUs). Mound and grave architecture, when present, was left in place until fully defined and documented and then removed if necessary. Baulks were drawn in profile and photographed and removed en masse at the end of each excavation., and Prior to excavation, all mounds surveyed in Shtoj and Shkrel were mapped and fully documented. The state of preservation (present day and projected into the future) of each mound was recorded (from poor to excellent, and from fully safe to critically endangered). Given that so many mounds in both regions were already damaged or had been destroyed, or were actively threatened, we decided to excavate mounds that were (1) already completely removed (T-085), (2) damaged by agricultural activities (T-052), (3) going to be removed by a landowner (despite legal prohibitions) (T-088), and (4) previously looted or excavated (T-099). We did not want to excavate seemingly intact, undamaged mounds. Our tumulus excavations can therefore be aptly described as “rescue” excavations.

Realm 2: Settlement Excavations

- Description:
- The PASH Data Collection is comprised of Five data “realms”: 1) Survey and site data, 2) Settlement excavations, 3) Tumulus (burial mound) survey and excavations, 4) Artifact analysis, and 5) Geological data. All databases, field notebooks, unit and profile drawings, photographs, photo descriptions, radiocarbon dates, and geophysical survey data related to the settlement excavations have been made available in PASH Realm 2. and The excavations we conducted at Kodër Boks, Zagorë, and Gajtan were designed to gather as much data as possible, as quickly as possible. They were composed of test pits (“units,” i.e., sondages), primarily 1x1 m in size, occasionally larger, positioned based on the results of field surveys and systematic surface collections of artifacts, but also with reference to prior excavations (at Zagorë and Gajtan) and geophysical data (collected at Gajtan). Excavations followed natural stratigraphy where possible; when such strata were not present, we excavated in 10-cm arbitrary levels. Artifact provenience was recorded down to levels and features, with important in situ artifacts sometimes being mapped into level/feature drawings along x-y-z axes. When identified, archaeological features (e.g., pits, floors, walls, etc.) were excavated separately from levels. Excavators organized forms and accompanying journal entries by “level” and “feature” for each unit. Each level and feature was drawn and photographed. Artifacts were bagged together by level and type. Radiocarbon samples were wrapped in tin foil and bagged separately. Soil samples were taken from each level using the “pinch” method. Upon completion, a profile wall of each unit was photographed, and, in some cases, drawn. Artifacts (with the exception of metal) were washed in water, dried on racks in the sun, and sorted and labeled in the PASH field laboratory. They were analyzed in preliminary fashion first in the field by PASH staff and later by experts.

- Description:
- The PASH Data Collection is comprised of Five data “realms”: 1) Survey and site data, 2) Settlement excavations, 3) Tumulus (burial mound) survey and excavations, 4) Artifact analysis, and 5) Geological data. All databases, drawings, photographs, photo descriptions, radiocarbon dates, and analytical data related to artifacts, ecofacts, and human remains have been made available in PASH Deep Blue Data Realm 4. Each artifact dataset will include all or some of the following: - Database files: CSV, Excel, PDF, Word; - Photos: Jpeg; - Drawings: PDF Total size of all files: approximately 10 gigabytes. See individual records or readme for linked chapters. and All artifacts found in the course of survey and excavation were brought to a museum facility in Shkodër (at the Hotel Meteor, on the Shkodër-Koplik road). They were cleaned, labeled, drawn, photographed, and described. Artifact descriptions were entered into one of three databases: pottery, chipped stone, and small finds. Each artifact was assigned a unique identifying number containing locational information. Pottery numbers typically begin with a tract or other collection unit (e.g., grid square in a site-surface collection) identifier, followed by a sequence number if more than one potsherd or ceramic was located in a tract or unit. Lithics and other small finds were assigned a GT number (GT-001, GT-002, etc.; GT being the Albanian acronym for Small Find). During a study season held in December 2014, artifacts were analyzed in more detail by specialists, each of whom produced a lengthier description of pottery, chipped stone, or small finds. A subset of ceramic and groundstone samples was retained for petrographic and chemical analysis. Finally, all seeds and wood charcoal recovered through flotation and all animal bones were analyzed. Human remains from Tumulus 99 were subjected to Strontium-isotope and aDNA analysis.

Realm 1: Field Survey and Site Collections
User Collection- Creator:
- Galaty, Michael
- Description:
- The PASH Data Collection is comprised of Five data “realms”: 1) Survey and site data, 2) Settlement excavations, 3) Tumulus (burial mound) survey and excavations, 4) Artifact analysis, and 5) Geological data. All databases, field notebooks, paper maps, GIS files, photographs, and photo descriptions related to the intensive survey, of tracts and tumuli, and the collection of sites have been made available in PASH Deep Blue Data Realm 1 (this sub-collection)., Over the course of five years, 11 field teams (Teams A–K) surveyed 2530 tracts in Shkrel and Shtoj, covering 16.1 km2. Survey data were eventually collapsed into six geographic zones (1–6). All tracts were surveyed using standard Mediterranean survey methods. For each tract (recorded consecutively by team letter and a number, e.g. A-001, A-002, etc.), surveyors walked at 15-m intervals and counted all tile/brick, ceramic fragments, and small finds. We conducted a full-coverage survey, meaning that all land forms—including fields, hills, and terraces—in each survey zone were surveyed, unless the landowner objected or the vegetation was so dense as to render survey impossible. Each tract was photographed and a GPS point at the center of the tract was obtained. Photos and photo descriptions were maintained in separate databases by each team. Information about tracts was recorded by hand in notebooks by team leaders. This included data about a tract’s soil, geology, ground cover (plants growing in the tract, crops planted in the field), associated structures, associated archaeological features (including tumuli), informant testimony, visibility, and, most critically, artifact counts. , and Realm 1 is divided into two sub-collections: Survey Data and Site Data. Both sub-collections are organized by data type. Survey data includes Tract photos and Photologs, Survey maps, Spatial data files, and a Collection Unit (CU) survey database. Site Data includes the Site database, Site documentation, Site photos and Photologs, and Spatial data files.

- Description:
- The PASH Data Collection is comprised of Five data “realms”: 1) Survey and site data, 2) Settlement excavations, 3) Tumulus (burial mound) survey and excavations, 4) Artifact analysis, and 5) Geological data. All of the geological data from cores and auger holes have been made available in PASH Deep Blue Data Realm 5. , Much of the work conducted by PASH took place on a geomorphic feature we call the Shtoj alluvial fan. Geological research was done along the distal margins of the Shtoj alluvial fan in the fringing freshwater wetlands of Shkodër Lake. Field reconnaissance in 2010 consisted of drilling twelve 5-cm diameter auger holes across the fan to a maximum depth of 4.8 m. A composite sediment sample was collected every 0.3 m during drilling. Between 2012 and 2014, sediment cores were taken at four wetland locations on the southeastern shore of Shkodër Lake. North-south trending core locations were selected following results of samples collected during the 2010 reconnaissance and are 1 km east of the Shkodër Lake shoreline. Twenty-two cores, ranging in length from 0.24 m to 0.87 m, were taken from four sites using a 6.3-cm diameter polycarbonate piston corer. , and (See readme in Geological Data record for full documentation; Chapter linked to: Chapter Two).

- Description:
- Data were collected while developing a management plan for eliminating nuisance algal blooms in a chain of reservoirs along the Huron River in southeastern Michigan. Federal funding was provided by both the U.S. EPA and the USDA. The river-reservoir system is used for municipal drinking water, wastewater disposal, irrigation, industrial processes, hydroelectric generation, sport fishing, and recreation. The impoundments episodically developed surface scums of cyanobacteria, contained microcystin toxins, and emitted foul odors including hydrogen sulfide. Past management strategy had focused on external phosphorus loading but failed to prevent nuisance conditions. Data collection and analysis pointed to the overwhelming role of internal nutrient loading and resulted in a series of whole lake experiments that destratified Ford Lake during summer and eliminated the nuisance conditions.

- Description:
- As part of the Flaring & Fossil Fuels: Uncovering Emissions & Losses (F3UEL) project, the aircraft measurement platform sampled downwind of flares in the Permian and Eagle Ford regions of Texas (2020) and the Bakken in North Dakota (2021). Estimates of methane destruction removal efficiency are calculated for each airborne intercept of a flare combustion plume based on the observed enhancements of carbon dioxide and methane, along with assumptions about the flare gas composition. Locations provided are the GPS coordinates for the aircraft sampling, not of the upwind flare infrastructure on the ground. Attempts to link the airborne sampling locations to ground infrastructure using the provided wind information (measured at the aircraft), should take care to account for complexities of transport in the atmosphere.

- Description:
- Rapid eye movement sleep (REM) is believed to have a binary temporal structure with “phasic” and “tonic" microstates, characterized by motoric activity versus quiescence, respectively. However, we observed in mice that the frequency of theta activity (a marker of rodent REM) fluctuates in a non-binary fashion, with the extremes of that fluctuation correlating with phasic-type and tonic-type facial motricity. Thus, phasic and tonic REM may instead represent ends of a continuum. These cycles of brain physiology and facial movement occurred at 0.01-0.06 Hz, or infraslow frequencies, and affected cross-frequency coupling and neuronal activity in the neocortex, suggesting network functional impact. We then analyzed human data and observed that humans also demonstrate non-binary phasic/tonic microstates, with continuous 0.01-0.04 Hz respiratory rate cycles matching the incidence of eye movements. These fundamental properties of REM can yield new insights into our understanding of sleep health.

F3UEL: Flaring & Fossil Fuels: Uncovering Emissions & Losses
User Collection- Creator:
- Kort, Eric and Plant, Genevieve
- Description:
- Fossil energy production, processing, flaring, and transmission all can harm climate and air quality by emitting greenhouse gases and air pollutants. Studies now show that onshore oil and gas production emit much more methane than what is inventoried, and that local air quality impacts can be significant, however, natural gas flaring and offshore systems have been largely overlooked. The F3UEL (Flaring & Fossil Fuels: Uncovering Emissions & Losses) project aims to address these gaps by improving our understanding of offshore emissions, characterizing how flares behave in the real world, identifying what portion of the offshore system is responsible for emissions, and determining how such systems can be monitored. Spanning three years (2020-2022), the project employed an aircraft platform to measure including both greenhouse gas and air quality measurements. To sample the largest regions of current and potential future offshore production and flaring, airborne measurements targeted the Gulf of Mexico, offshore California and Alaska, the Bakken Formation (North Dakota) and the Permian and Eagle Ford Basins (Texas). Data provided here includes the airborne measurements collected using Scientific Aviation’s Mooney aircraft platform, equipped with spectroscopic instrumentation to measure methane, carbon dioxide, water vapor, nitrous oxide, and nitrogen oxide, in addition to meteorological variables such as wind speed and direction. Data products from our analysis of these airborne measurements are also provided, including estimated flare destruction removal efficiency for the Bakken, Eagle Ford, and Permian basins. Each data file is in .csv format and is accompanied by a readme file with further information and descriptors of the variables included. All users should cite the papers and datasets provided in the readme files for each individual dataset. Website: https://graham.umich.edu/f3uel This project is funded by the Alfred P. Sloan Foundation with additional support from the Environmental Defense Fund, Scientific Aviation, and University of Michigan (College of Engineering, Climate and Space Sciences and Engineering; Graham Sustainability Institute).

- Description:
- Large geomagnetic disturbances (GMDs, also denoted as MPEs - magnetic perturbation events) have sufficient amplitude to cause geomagnetically induced currents (GICs) that can damage technical infrastructure. In this study we present occurrence statistics for GMD / MPE events with derivatives ≥ 6 nT/s and ≥ 20 nT/s from five stations in the MACCS and AUTUMNX magnetometer arrays in Arctic Canada at magnetic latitudes ranging from 65° to 75°. Earlier studies using data from these arrays (Engebretson et al., 2019a,b, 2021a,b) covered only two years (2015 and 2017) and focused on latitude- and local time-dependent occurrence patterns and short-term dependencies on solar wind/IMF parameters and magnetospheric activity indices. This study presents all available data from these stations from 2011 through 2022 to analyze variations of GMD activity over a full solar cycle. Intense GMD activity did not closely follow the sunspot cycle, but instead was lowest during its rising phase and maximum (2011-2014), was highest during the early declining phase (2015-2017), and reached a subsequent minimum early in the following sunspot cycle (2020). GMDs with amplitude >20 nT/s followed the same yearly pattern but peaked even more strongly during 2015-2017. Most of these GMDs were associated with high-speed solar wind streams (Vsw > 600 km/s), but not with strongly negative values of the SYM/H index. The majority of these GMDs, irrespective of the Vsw value, were accompanied within 10 min (and most often less) by other events with amplitude ≥ 6 nT/s and showed a mostly poleward progression. These results show that large amplitude but spatially localized nighttime GMDs are primarily associated with high-speed stream geomagnetic drivers during the declining phase of the solar cycle. This indicates that large GIC hazard conditions can occur for a variety of solar wind drivers and geomagnetic conditions and not only for fast-coronal mass ejection driven storms.

Supporting data: Domain-agnostic predictions of nanoscale interactions in proteins and nanoparticles
- Creator:
- Saldinger, Jacob, Raymond, Matt , Elvati, Paolo, and Violi, Angela
- Description:
- The accurate and rapid prediction of generic nanoscale interactions is a challenging problem with broad applications. Much of biology functions at the nanoscale, and our ability to manipulate materials and purposefully engage biological machinery requires knowledge of nano-bio interfaces. While several protein-protein interaction models are available, they leverage protein-specific information, limiting their abstraction to other structures. Here, we present NeCLAS, a general, and rapid machine learning pipeline that predicts the location of nanoscale interactions, providing human-intelligible predictions. Two key aspects distinguish NeCLAS: coarse-grained representations, and the use of environmental features to encode the chemical neighborhood. We showcase NeCLAS with challenges for protein-protein, protein-nanoparticle and nanoparticle-nanoparticle systems, demonstrating that NeCLAS replicates computationally- and experimentally-observed interactions. NeCLAS outperforms current nanoscale prediction models, and it shows cross-domain validity, qualifying as a tool for basic research, rapid prototyping, and design of nanostructures., Software: - To reproduce all-atom molecular dynamics (MD) NAMD is required (version 2.14 or later is suggested). NAMD software and documentation can be found at https://www.ks.uiuc.edu/Research/namd/, - To reproduce coarse-grained MD simulations, LAMMPS (version 29 Sep 2021 - Update 2 or later is suggested).

- Our research focuses on providing a fully-imputed map of the worldwide total electron content with high resolution and spatial-temporal smoothness. We fill in the missing values of the original Madrigal TEC maps via estimating the latent feature of each latitude and local time along the 2-D grid and give initial guess of the missing regions based on pre-computed spherical harmonics map. The resulting TEC map has high imputation accuracy and the ease of reproducing. and All data are in HDF5 format and are easy to read using the h5py package in Python. The TEC map is grouped in folders based on years and each file contains a single-day data of 5-min cadence. Each individual TEC map is of size 181*361.

- Description:
- The NASA MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft, which is currently in orbit around Mars, has been taking daily (systematic) measurements of the densities and temperatures in the upper atmosphere of Mars between about 140 to 240 km above the surface. Wind measurement campaigns are also conducted once per month for 5-10 orbits. These densities, temperatures and winds change with time (e.g. season, local time) and location, and sometimes fluctuate quickly. Global dust storm events are also known to significantly impact these density, temperature and wind fields in the Mars thermosphere. Such global dust storm period measurements can be compared to simulations from a computer model of the Mars atmosphere called M-GITM (Mars Global Ionosphere-Thermosphere Model), developed at U. of Michigan. This is an ongoing detailed comparison between direct global dust storm period measurements in the upper atmosphere of Mars and simulated MGITM fields and is important because it can help to inform us what physical processes are acting on the upper atmosphere during such large dust events. Since the global circulation plays a role in the structure, variability, and evolution of the atmosphere, understanding the processes that drive the winds in the upper atmosphere of Mars also provides key context for understanding how the atmosphere behaves as a whole system. A basic version of the M-GITM code can be found on Github as follows: https:/github.com/dpawlows/MGITM [less] About 4 months of Neutral Gas and Ion Mass Spectrometer (NGIMS) measurements of densities and winds have been made by the MAVEN team during the summer of 2018 (Elrod et al., 2019; Roeten et al 2022). For this specialized archive (Elrod et al. 2023), one reference measurement interval during this 2018 global dust storm (30-31 August 2018) is selected for detailed study of helium distributions (Elrod et al. 2023). The Mars conditions for this last of nine intervals have been used to launch corresponding M-GITM code simulations, yielding 3-D neutral density, temperature and wind fields for comparison to these NGIMS measurements. This last interval is used to provide M-GITM datacubes to explicitly extract the helium density (plus corresponding temperatures and neutral winds) along the trajectory of each orbit path between 140 and 240 km . A general README file is also provided for this Deep Blue Data archive detailing the contents of each file, while also summarizing the inputs and outputs of the M-GITM code simulations for this study.

- Description:
- The data and scripts are meant to show how burster dynamics determine response to a single biphasic stimulus. The files include data which show trends in the propensity of termination for different burster types and the MATLAB scripts used to generate this data. The MATLAB scripts also allow the user to generate their own data sets for alternative bursting paths and stimulus parameter combinations. Furthermore, they allow the user to visually examine the effects of single stimuli in the voltage timeseries and in state space. How the user can access these features of the script is described in the file "ReadMe.pdf."

- Description:
- In this work, we perform Global Sensitivity Analysis (GSA) for the background solar wind in order to quantify contributions from uncertainty of different model parameters to the variability of in-situ solar wind speed and density at 1au, both of which have a major impact on CME propagation and strength. Scripts written in the Julia language are used to build the PCE and calculate the sensitivity results. Data is available in csv, NetCDF and JLD files. A `Project.toml` file is included to activate and install all required dependencies (See README for details).

- Description:
- It is commonly thought that volcanic glass only records volatile loss during the eruptions in the Moon. However, our recent work shows that Na, K and Cu (moderately volatile elements) in lunar 74220 orange glass beads are enriched near the bead surfaces and depleted in the bead interiors, forming an overall “U-shaped” profile. The “U-shaped” profile means that rather than being “lost” into space, Na, K and Cu were “gained” into the volcanic glass during the eruption, which is contrary to the “volatile loss” story. Three different instruments (EMP, SIMS and LA-ICP-MS) were used to verify the discovery. We propose that such U-shaped Na, K and Cu profiles were formed by initial outgassing and subsequent in-gassing of Na, K and Cu when the beads were flying from the vent onto the surface through the cooling volcanic gas plume. Hence, in-gassing and the formation of surface coatings are two processes that are genetically linked during the pyroclastic eruption and evolution of the gas cloud. To quantify the processes that formed the U-shaped profiles, we developed a diffusion and surface-equilibrium model using available literature data on Na and Cu diffusivity in basaltic melts. The model reproduced U-shaped Na and Cu concentration profiles with outgassing at high temperature and subsequent in-gassing as beads cooled. By fitting the measured Na and Cu profiles, we found that the cooling time scales of individual orange glass beads range from 48 to 179 s. This is the first time that both outgassing and in-gassing were modeled and the cooling time scales of individual 74220 volcanic orange glass beads were estimated. The discovery of the U-shaped profiles of moderately volatile elements inside volcanic beads provides significant constraints on partial pressures of relevant volcanic gas species in the eruption plume.
