[ncl-talk] About regridding from

[Barry Lynn]

Hi Tao:

Here, I gridded the radar data to the WRF grid.

You will need to adapt what I did to your situation, but the most important
step is to decide on the degree of smoothing (which is set by rscan).

 grid = obj_anal_ic(lon_o,lat_o,obs_o,xlon_m,xlat_m,rscan,False)

Please write if you have questions.

Barry
