Archived Radar Coded Message (RCM) Data Maps

Radar Coded Message (RCM) summaries are composites of high resolution NEXRAD reflectivity data that have been mapped to 10-km gridded resolution. This process loses some detail, but it still provides much finer resolution than corresponding Manually Digitized Radar (MDR) report-based maps. RCM reports also are provided every half-hour compared to the hourly frequency of MDR reports.

  • Archived RCM radar data only go back to February 11, 2002.
  • RCM data maps are more detailed than corresponding MDR maps.
