I want to use the WRF to simulation the polarization weather radar echo data.which parameters your .nc datas contains and how do you conversion the weather echo data to the .nc datas

tjlang commented 8 years ago

You will need to use a forward operator to convert the microphysical information from WRF to radar observables. This can be tricky business since usually the microphysics is parameterized in some way, and that creates ambiguities. But it has been done. Here is an example from the literature: http://journals.ametsoc.org/doi/abs/10.1175/2008JAMC1793.1

Key to any forward operator is employing scattering calculations to convert the microphysical information to polarimetric variables like ZDR and KDP. Here is a good place to start with that: https://github.com/jleinonen/pytmatrix

Once you have WRF converted to radar observables, then you may employ CSU_RadarTools for analysis (e.g., HID). Good luck!

Thank you very much! I know the U.S is in the morning. Have a nice day!
