Abstract :
A relationship linking rainfall rate with powers of radar reflectivity and specific attenuation is considered. It is shown that at frequencies used for the spaceborne monitoring of rain, such a relationship exists that is relatively insensitive to dropsize distribution (dsd) and temperature over a wide range of rainrates
