Radar Control 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.
