[ncl-talk] Station obs overlay on map

[Debasish Hazra]

 Grib2 input is big to attach, here is the link of actual file (take any
day or forecast hours) :
https://nomads.ncep.noaa.gov/pub/data/nccf/com/gens/prod/gefs.20260718/00/chem/pgrb2ap25/
I am getting error in this line : lat_new(i,0:npts_range-1) =
obs_lat(indexes)
error says : fatal:Subscript out of range, error in subscript #0
fatal:["Execute.c":8637]:Execute: Error occurred at or near line 68 in file
Test_read.ncl

Thanks,
Debasish
