The Hive: University of Utah Research Data Repository. https://doi.org/10.7278/S5d-n1jc-2d68. --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: Highland_MRR_NetCDF_2022_2024.zip Short description: This is a directory containing files using the following naming conventions: processed_Highland_[YYYYMMDD]_030m.nc and processed_Highland_[YYYYMMDD]_180m.nc. Within this directory, there are 2 files for each calendar day, with the day being defined in UTC. The 1st file will have a "30m" suffix indicating that the data is using 30m range gates. The 2nd file will have a "180m" suffix indicating the data is using 180m range gates. 2. Relationship between files: NA 3. Additional related data collected that was not included in the current data package: NA 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: The Metek Micro Rain Radar (MRR) was fixed to a 1m tall tripod on the roof of Highland High School, and was pointed within 1.5 degrees of vertical (generally within 1.0 degree) for the entire dataset period. There was a heater operated on the dish to mitigate snow accumulation, and there were no documented periods in which this heater was insufficient to keep the dish snow-free. Contact the authors for more information. 2. Methods for processing the data: The raw MRR files were processed using the method of Maahn and Kollias (2012) to improve their usability for the low reflectivity values typical of snowfall. They were then converted to NetCDF format. 3. Instrument- or software-specific information needed to interpret the data: NetCDF files can be read using a variety of open-source software. For a quick look at the data, we suggest NCview. For processing and analysis, various python packages are best. 4. Standards and calibration information, if appropriate: NA 5. Environmental/experimental conditions: The Metek Micro Rain Radar (MRR) was fixed to a 1m tall tripod on the roof of a high school, and was pointed within 1.5 degrees of vertical (generally within 1.0 degree) for the entire dataset period. There was a heater operated on the dish to mitigate snow accumulation, although occasionally this was insufficient. 6. Describe any quality-assurance procedures performed on the data: NA 7. People involved with sample collection, processing, analysis and/or submission: NA ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: Highland_MRR_NetCDF_2022_2024.zip ----------------------------------------- 1. Number of variables: Inside Highland_MRR_NetCDF_2022_2024.zip, there are 2 files for each day. Within each of these files, there are 4 variables. 2. Number of cases/rows: Each file (processed_Highland_[YYYYMMDD]_030m.nc OR processed_Highland_[YYYYMMDD]_180m.nc) contains approximately 700 radar scans during the 24 hour period that it encompasses. 3.
