This dataset includes files from the National Severe Storms Laboratory mobile mesonets operated during the LAPSE-RATE field campaign. Daily files from each operation day are uploaded, along with a readme file explaining the format and processing. Version 2 Notes: The original version of this upload contained files with incorrect QC flags. While the core data is correct, the QC flags can be useful for determining specific areas of interest or problems. After identifying this issue, the files were reprocessed to include the correct QC flags and were uploaded to the archive as Version 2. Any questions should be directed to sean.waugh@noaa.gov.
