Hi @davis-wesley-12345.

I think we have found the source of the problem. It looks like in your configuration file, Standard_GridStatConfig_NAVGEM_2020040112, you have the following:

climo_mean = {

   file_name = [ "/p/work1/daviswj/UV-126/uv/nrl/veriftools/data/climo_emc_ncep_noaa/NCEP_1.0deg/cmean_1d.19790401" ];
   field = [
      {
         name  = "";
         level = [""];
         cat_thresh = [];
      }
   ];

and the file "cmean_1d.19790401" is a GRIB file.

However,

level = [""];

is not an empty array, but rather an array of length one that contains only an empty string.

Setting

file_name = [ ]; 

should fix this error. However, if you do intend to use climatology data you will need to provide further information, including the name and level information.

I hope that helps!

It did help and you're wonderful. Thank you!
