## WSR-88D Z/R Relationship Table | |||||||

This table shows WSR-88D Z/R relationships for sites used in the
North Central River Forecast Center Multisensor Precipitation radar mosaic.
A Most stratiform rain has a reflectivity signal strength of 20-40dBZ with peaks to 45dBZ, but rarely anything higher (that isn't "brightbanding"). For more information, authorization, instructions, and recommendations regarding Z/R relationships, see the Radar Operations Center's page. | |||||||
