[ncl-talk] ESMF_regrid_gen_weights error

[Vollaro, David]

Hi,

I am trying to read in a grib2 datafile and convert it to a KML file.  I am following  the rastertimeseries2kml
script from the NCL_GETools API page (https://www.ncl.ucar.edu/Document/Manuals/GETools/NCL_GETools.html)

Here is the Logfile PET0.RegridWeightGen.Log contents:

It generates tmpDstGrid.nc, and tmpSrcGrid.nc.  I believe the errors arise when trying to generate a weight file.
 Here is a snippet of my code.  The data is on a 3500x7000 grid at 0.1deg.
         La1 :  54.995
         Lo1 :  230.005
         La2 :  20.005
         Lo2 :  299.995
         Di :   0.009999999
         Dj :   0.01
Lat is in degrees_north Lon in degrees_east. I am running NCL 6.5.0

Below is a snippet of my code.  Thanks

Dave
