Radar Chart
The Radar Chart collection is an archived product of summarized radar data. The geographic coverage is the 48 contiguous states of the United States. These hourly radar charts were prepared by the National Weather Service (NWS) and the National Centers for Environmental Prediction. Data contains analyzed areas, lines, and cells of cloud formations that include the base, tops, movement, and precipitation intensity. Precipitation types and change of intensity are also depicted. These charts are prepared from radar observations taken by NWS weather radar stations throughout the country.
