Radar Data

There are several types of radar data including Manually Digitized Radar (MDR), Radar Coded Messages (RCM) and NEXRAD data (NIDS). These data come from meteorological radars placed at various locations across the US. The RCM messages are combined into a national mosaic which is what is presented below. The images are updated twice an hour at :05 and :35.
