Doppler radar has a detection range of ~400 kms. It can transmit information about a cloud, its distance from land, its composition, which direction it is moving and even minute details like the number and size of water droplets found in a cloud. We can predict the amount of rainfall to an area, 2-3 hours in advance.
Currently, QPE studies based on weather radar only consider the reflectivity factor at each point.

Cloud radar Doppler spectra have been commonly used for cloud property retrieval and microphysical studies because of their wealth of information on drop size distribution, turbulence, vertical air motion, and so on. However, Doppler spectra simultaneously contain radar noise and meteorological signals, ... Doppler radar pulses have an average transmitted power of about 450,000 watts. By comparison, a typical home microwave oven will generate about 1,000 watts of energy. Yet, each pulse only lasts about 0.00000157 seconds (1.57x10 -6 ), with a 0.00099843-second (998.43x10 -6 ) "listening period" in between. Measurements taken with a vertically pointed Doppler radar and coincident estimates of cloud optical thickness from IR brightness temperature can be used to retrieve vertical profiles of microphysical parameters such as particle characteristic size and cloud ice water content [e.g., Matrosov, 1997].
