[ncl-talk] Reading NETCDF files OK with NCVIEW but Not Working in NCL (Ruben Santos)

[Elizabeth Burakowski]

Hi Ruben,

You may need to list the files first:

fils = systemfunc("ls PATHTOFILES/*radar.nc")
ra = addfiles(fils,"r")

To read off the variable, you would then need the following:

accum = ra[:]->ACCUM_Z_ZDR

See Example 1:
