These products reveal the highest reflectivities in all echoes, examine storm structure features, and determine the intensity of storms.Ĭomposite Reflectivity is a display of maximum reflectivity for the total volume within the range of the radar. Data values are actual reflectivity values (uses the 0.5 degree elevation cut).Ĭomposite Reflectivity is a display of maximum reflectivity for the total volume within the range of the radar.

Scientists use these products to detect precipitation, evaluate storm structure, locate boundaries, and determine hail potential. Data values are actual reflectivity values (uses the 0.5 degree elevation).Ī display of echo intensity measured in dBZ (with ground clutter / non-precipitation echoes removed). Scientists use these products to detect precipitation, evaluate storm structure, locate boundaries, and determine hail potential. 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. Storm-based warnings display by default on the 'National radar mosaic' and 'Radar station products' views. See changes in downloads for more information.

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. Welcome to FAQs about the National Weather Service’s new radar webpage located at and launched on December 17, 2020.
