[ncl-talk] Error: ESMF to map 10min to 30 sec

[Sarah Bradley - CITG]

Hi Rick

Thank for the suggestions: However I have tried both of this choices and “Largefileformat” in the setfileoption and I still receive the same error message

Hi Sarah,

I'm not expert at this, but it sounds like you might be writing a variable larger than 2GB?  This FAQ from Unidata specifically mentions the error message you are getting:

    https://www.unidata.ucar.edu/software/netcdf/faq-lfs.html

I see you are using "NetCDF4Classic" in your setfileoption calls, and I *think* that has the 2GB limit that NetCDF3 has -- it may be the case you need to use either "NetCDF4" or "64BitOffset" instead to write large variables.

Hope that helps...
Rick

Hello

I am trying to map a 10min global file to a 30 sec grid using the ESMF mapping software

I have attached my ncl script

fatal:["Execute.c":8640]:Execute: Error occurred at or near line 90 in file remap_10min-30sec_ESMF.ncl

I found that as the 30sec file was large, I needed to specify this in the script.

I hope you can help,

Sarah Bradley
