    • NOAA Next Generation Radar (NEXRAD) Level 1 Event Data

    Metadata Updated: September 19, 2023

    This dataset contains the Level 1 (L1) raw radar event data recorded at Next Generation Radar (NEXRAD) sites and collected by the NOAA National Weather Service (NWS) Radar Operations Center (ROC) for specific radar case studies. It includes only the Level 1 data that has been used for algorithm development and verification by the ROC and its partners. NEXRAD operational sites and test sites are used. The dataset period of record starts in 2008 with new data added approximately every year. The number of case studies per year ranges from 1 to 33, with an average of approximately 10 per year. The data files are in the native compressed file format as Time Series (TS) Archive. The data files have been aggregated by event and by hour for the archive with a total data volume of approximately 20 TB. An event summary file with descriptive information is included for each case study.
