Re: Regridding Daymet Joined Tiles with ESMF_Regridding on NCL 6.1.0

Hi NCL,

For both the Example 2 and Example 3, I tried to find the destination file:

;---Set the destination file name
    dstDirName = "./"
    dstFileName = str_upper(vname)+"."+year+"_"+tile+".esmf.nc"
    dstPathName = dstDirName+dstFileName

Which were supposed to be: PRCP.2010_12296.esmf.nc

However, I didn't get it.

How can I get the regrided output file? I was suggested that the file will
be generated by default(no need the dstFile=addfile(dstPathName, "c"))

Thanks,

Ping
