![]() Cool colors (green) represent negative values and warm colors (red) represent positive values. SR_BVEL (Super Resolution Base Velocity)Ī measure of the radial component of the wind either toward the radar (negative values) or away from the radar (positive values).Data values are actual reflectivity values in dBZ of the 0.5 degree elevation scan. Scientists use these products to detect precipitation, evaluate storm structure, locate boundaries, and determine hail potential. ![]() SR_BREF (Super Resolution Base Reflectivity)Ī display of echo intensity measured in dBZ.Scientists use this product for a quick estimation of the most intense convection and higher echo tops, as an aid in identification of storm structure features, and for pilot briefing purposes. TC: Tropical Convective TS: Tropical Stratiform CS: Cool Stratiform H: Hail C: Convective S: Snow WS: Warm StratiformĪn image of the echo top heights color-coded in user-defined increments in thousands of feet. The primary use of the SPT is for automatic selection of Z-R relationships and for computing Surface Precipitation Rates (SPRs) from the Seamless Hybrid Scan Reflectivity (SHSR) mosaic. Data values are in dBZ.Īlgorithm which classifies radar echoes into one of seven categories: 1) warm stratiform rain, 2) cool stratiform rain, 3) convective rain, 4) tropical/stratiform rain mix, 5) tropical/convective rain mix, 6) hail, and 7) snow. With ground clutter / non-precipitation echoes removed. These products reveal the highest reflectivities in all echoes, examine storm structure features, and determine the intensity of storms. Data values are actual reflectivity values (uses the 0.5 degree elevation) in dBZ.Ĭomposite Reflectivity is a display of maximum reflectivity for the total volume within the range of the radar. You can select to display all warnings on these views by using the view options (three vertical dots).įor national mosaics (Conus, Alaska, Hawaii, Guam and Puerto Rico):Ī display of echo intensity measured in dBZ (with ground clutter / non-precipitation echoes removed). Storm-based warnings display by default on the "National radar mosaic" and "Radar station products" views. See changes in downloads for more information. Dual-Pol Differential Reflectivity (BDZD).The following radar products were removed per SCN 23-61: Topo, counties, rivers, highways, cities.Select the map options and then choose "Reset Map." Map legend for the selected radar product(s).Map time for the selected radar product(s).Common help for the National Weather Service sites.Application menu customized for the radar site.How can I get standard radar/animated GIF's (for low bandwidth users)?.How do I consume OGC compliant service in my own application?.Why do I get a blank/no Image when loading a radar?.How do I get information on other OGC GIS Services available?.How do I display radar for my location?.If you have suggestions or feedback, please email Last Updated: 9/6/23 for Version 2.0 updates. Our GIS-based webpage allows users to integrate our radar data into their own platforms. On the new page, we provide more radar products and radar images are updated more frequently and at four times higher resolution than before. ![]() We redesigned our radar viewer to improve our services to the public.
