Thank you for using Rain Viewer’s Weather Maps API. We appreciate your understanding as we focus our efforts on delivering the best precipitation prediction through our consumer applications.

All available color schemes for the past and future radar data. For the infrared satellite data, only one (0) default color scheme is available.

Important: Starting January 1, 2026, only the Universal Blue color scheme (ID: 2) will be available via our API.

Black and White dBZ Values

Shows raw dBZ values starting from the -31 dBZ (pixel’s red component color “1” value) and ending at 95 dBZ (“127” value) with 1 dBZ step (see table below). If snow options are selected, the first bit in the sub-color byte provides the snow mask. For example, if a red component is 175 it means snow with reflectivity 15 dBZ. 175 & 128 = 128 - snow mark. 175 & 127 = 47 - red pixel value. 47 - 32 = 15 dBZ. If the pixel is transparent, there is no data for it or -32 dBZ.

Color Tables for Each Color Scheme

Color format is HEX RGBA. All color schemes also available for download as CSV file.
