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.

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).

Projekti Arkeologjik i Shkodrës (PASH)
User Collection- Creator:
- Galaty, Michael
- Description:
- The data presented here were collected in the course of archaeological survey and excavation in the region of Shkodër in northern Albania, carried out between 2010 and 2014, with a follow-up visit in 2016. The Projekti Arkeologjik i Shkodrës (PASH) was co-directed by Michael L. Galaty (University of Michigan) and Lorenc Bejko (University of Tirana) and was sponsored by the United States National Science Foundation (NSF BCS1220016), The University of Tirana, Millsaps College, Mississippi State University, and the University of Michigan. The data presented here accompany a two-volume research report, published by the University of Michigan Museum of Anthropological Archaeology Press (Galaty and Bejko 2023) - Volume 1 ( https://doi.org/10.3998/mpub.12201317) and Volume 2 ( https://doi.org/10.3998/mpub.12208577)., The county (Alb. qarqe) of Shkodër is located in northern Albania. It is bordered to the south by the Adriatic Sea and to the northwest by the country of Montenegro. The counties of Lezhë and Kukës are situated to the south and east, respectively. Shkodër Lake is situated along the border with Montenegro. It is the largest freshwater lake in the Balkans. The city of Shkodër is the fifth largest in Albania. It was founded in the Bronze Age and became a Roman colony in 168 BC, following the Illyrian Wars. Several major rivers intersect at Shkodër, including the Buna, which exits Shkodër Lake, the Drin, and the Kir. The latter two rivers flow from the Bjeshkët e Nemuna, the Albanian Alps, and provide access across the mountains, to the Balkan interior, including metal-rich Kosovo. Several very important ancient sites are located to the south of Shkodër, close to the Adriatic coast: Lezhë (ancient Lissus), Apollonia, and Durrës (ancient Epidamnus, Dyrrachium under the Romans). The latter two cities were Greek colonies, founded during the Archaic period. All three became Roman colonies., and PASH was designed to investigate shifts, through time, in Shkodër towards increased social stratification and hierarchy. These shifts commenced during prehistory and are marked by two dramatic changes in the regional landscape: new settlement in defensible “hillforts” and burial in rock and earth mounds. We wondered what factors – environment, settlement, status, conflict, subsistence, trade, migration – might have allowed or encouraged these changes.

Realm 5: Geological Data
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 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).

Realm 4: Artifact Analysis
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, 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.
