I am trying to map local emissions to WRF-Chem. The projection of local emission is in UTM, how to convert to GCS. Here is the ncdump of the file showing some details below. I tried with cdo but hard luck. Can any one help to resolve this issue to make the nc file compatible to use in the anthro emis tool.

ncdump -h HH_final_emis.nc

netcdf HH_final_emis {
