Associated terrain data were publicly available through USGS.
Beam heights were calculated using a standard atmospheric refractive index of 1.21 and the Half-Power Beamwidth. Radar Radar with Surface Map Radar with U.S. Maps, below, show existing radar locations and full volumetric coverage for all operation NEXRAD WSR-88D and TDWR sites.

United States High Resolution 24 Hour Animated Radar Loop National Radar with Rain, Sleet, Hail and Snow Indicated Animation: None 1Hr 2Hr 6Hr 12Hr 24Hr 24hr Radar Loop Options U.S. On mobile devices, you can save the bookmark as an easy-access icon similar to other apps. For example, if you select "Weather for a location," then select a location, the bookmark will return to your location on your next visit. You may bookmark the URL to return later to the same view with the selected settings. The URL will automatically update as you select the view and settings. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. If the radar animation of the last hours shows local thunderstorms or precipitation cells forming and disappearing in an irregular manner, then the forecast is not vey accurate.This site is organized into views that provide relevant radar products and weather information for a common task or goal. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created. The Current Radar map shows areas of current precipitation (rain, mixed, or snow). Real weather is more complex than just the displacement of existing precipitation cells. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future. ( a ) If an ap- plicant elects to use a Doppler Radar System it must be. United States: How accurate is the radar based forecast? Equipment and equipment installa- tion - Doppler Radar Systems. See the latest United States Doppler radar weather map including areas of rain, snow and ice. Export Citation: Click for automatic bibliography generation. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually. The different colours indicate the intensity of rainfall or snowfall. The radar map is updated every 5 minutes with a new radar observation. Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. Pulsed doppler radar methods and apparatus. The weather radar ( United States) shows where it is currently raining or snowing. Note that lightning is not shown on the forecast, as it cannot be predicted. Doppler Radar National Mosaic - NOAAs National Weather Service. Switching to radar only mode in the layers menu will update the image every 5 minutes. Doppler radar / satellite mode set to update an image every 15 minutes. Weather radar is fixed on the State of Florida but can be panned /zoomed to different locations. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms.Ĭurrent lightning strikes are marked with small orange dots on the map (Europe only). Additional layers and features are located in the Layers menu (bottom right).
