CAPS Polarimetric Radar data Simulator (CAPS-PRS)
CAPS-PRS is a general purpose polarimetric radar data simulator developed
at CAPS for nonhydrostatic weather prediction models with explicit
microphysics schemes. User interface and driver are written in Python
while complex scattering amplitude calculation makes use of Fortran code.
Current CAPS-PRS is a beta version 1.0 and was released to the public,
furnished as it is, in 2015.
The CAPS Polarimetric Radar data Simulator (CAPS-PRS)
resides in the public domain and may be used free of charge,
and without restriction .
Registration, with accurate name, address, phone number, and email address,
