- Description:
- Archives at the Institute for Fisheries Research (IFR) hold meticulous records of thousands of lake surveys from the University of Michigan and Michigan Department of Natural Resources. Starting more than a century ago, surveys have been used to understand how fish were distributed across the state, which lakes would support sportfishing, and how lakes should be managed. We can now use these records of lake conditions and fish abundance and growth to understand how climate change and other factors have impacted fish communities. and The records contained in this collection are digitized records from the IFR surveys stored as jpeg image files. This collection includes information on both lake factors (e.g. depth, nutrients, temperature) and fishes (e.g. species, catch, length). Scanned cards were organized by card type and each dataset in this collection is for a specific card type.

- Description:
- Archives at the Institute for Fisheries Research (IFR) hold records of thousands of lake surveys from the University of Michigan and Michigan Department of Natural Resources. The records contained in this dataset are jpeg images of the index card records from the IFR surveys. Images include the front of the card and when available, the back of a card. and Lake Summary cards include information about the lake location and its characteristics, such as lake depth, water chemistry, water color, and transparency (commonly measured as Secchi depth). There is information on surrounding characteristics such as its connectivity to other waterbodies, shoreline conditions, and surrounding land-use. This card also lists the fishes present in the lake and makes observations about fishing pressure, parasites, and reproduction.

The records contained in this dataset are jpeg images of the index card records from the IFR surveys. Images include the front of the card and when available, the back of a card. and Fish Growth Cards report information on the age and length of fishes captured in lake surveys. The age of a fish was determined by counting annual rings on hard structures including scales, spines and otoliths (fish ear bones).

- Description:
- In this study, we took advantage of the randomized allocation of the US EPA's funding for school bus replacements and retrofits to causally assess the impacts of upgrading buses through the EPA’s national School Bus Rebate Program on attendance, educational performance, and community air quality (PM2.5). Specifically, we used classical intent-to-treat analyses for randomized controlled trials to compare the changes in school district average attendance, test scorers (reading language arts and math), and PM2.5 levels after vs before the 2012 through 2017 lotteries by funding selection status.

- Description:
- The file named "Raw_Reference+OIDU_Data.xlsx" contains both raw data from the Phenom 300 reference scientific measurements and raw data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. Each tab of the file named "Raw_Reference+OIDU_Data.xlsx" contains data from a specific flight with the flight number in the tab. Each tab contains columns for measurement time (in seconds of the UTC day), 905 nm OIDU signal (in counts), 1525 nm signal (in counts), 1635 nm signal (in counts), flight altitude (in ft), air temperature (in degrees C), liquid water content -LWC (in g/m^3), total water content -TWC (in g/m^3), ice water content -ICW (in g/m^3), and median volume diameter -MVD (in micron)., The file named "Raw_MRU_Data.xlsx" contains raw data from measurements made by the microwave resonator unit (MRU). The various columns contain data from engineering measurements and icing detection measurements. The data scientific relevant are in column A -the time stamp in UNIX time, column B -the time stamp in seconds of the GMT day, column G -the peak resonator frequency (Hz), and column H -the resonance quality factor (non-dimensional)., and The file named "Appendix-C-O_Data_Explained.xlsx" contains processed data from measurements by the Phenom 300 reference scientific measurements and processed data from measurements by the Icing Detection System (IDS) Optical Icing Detection Unit (OIDU) installed in the Phenom 300. As explained in Renno et al. (2025), the raw data was reduced by removing data points reported to contain measurement errors (identified by the NAN code in the data) and in-cloud measurements in which TWC ≤ 0 or MVD ≤ 0 before being analyzed. Each data column is described in the first tab.

- Description:
- The ability to accurately measure tibiofemoral angles during various dynamic activities is of clinical interest. The purpose of this study was to determine if inertial measurement units (IMUs) can provide accurate and reliable angle estimates during dynamic actions. A tuned quaternion conversion (TQC) method tuned to dynamics actions was used to calculate Euler angles based on IMU data and these calculated angles were compared to a motion capture system (our “gold” standard) and a commercially available sensor fusion algorithm. Nine healthy athletes were in-strumented with APDM Opal IMUs and asked to perform nine dynamic actions; five participants were used in training the parameters of the TQC method with the remaining four used to test validity.

- Description:
- Reconstructed CT slices for Cranium of Castoroides (University of Michigan Museum of Paleontology catalog number UMMP VP 3110) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data resulting from a merge of two separate scans are offered here as a series of unsigned 16-bit integer TIFF images. There may be slight differences in voxel grey values between the two parts. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
