VORTEX-2 2009-2010 radar data from NOAA X-band dual Polarimetric radar (NOXP)

This dataset provides level 2 radar data collected by NOAA X-band dual Polarimetric radar (NOXP) during Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX-2) in 2009-2010.

Archive file names have form  YYYY.NOX.sweep.MMDD.tar.gz, where YYYY denotes year, MMDD denotes month and day. Extracting the archive with a unix command like

tar zxf YYYY.NOX.sweep.MMDD.tar.gz

produces a directory tree in the current working directory. Data files are in paths of form:

YYYY/NOX/sweep/MMDD/NOXYYMMDDHHMMSS.RAW????/swp.YYYMMDDHHMMSS.NOXPRVP.d.dd.0_PPI_v1

where YYYY denotes year, MMDD denotes month and day, NOXYYMMDDHHMMSS.RAW???? identifies the radar volume (cycle of antenna pointing angles), and swp.YYYMMDDHHMMSS.NOXPRVP.d.dd.0_PPI_v1 denotes a file with data for one sweep (cycle of antenna pointing angles with the same elevation (PPI) or azimuth (RHI)). YYY is number of years since 1900. d.dd is the sweep angle.

The sweep files are DORADE format, documented at https://www.eol.ucar.edu/sites/default/files/files_live/private/files/field_project/EMEX/DoradeDoc.pdf . RadxConvert, which is part of lrose (https://ncar.github.io/lrose-core), can rewrite the files in other formats as needed by other software.
