Hope you will be able to advise, I have generated my own gridded emissions files for CMAQ (not using SMOKE) as I needed some very spesific temporal and species profiles applied . I have generated a NetCDF file using the global attributes of the MET_CRO_3D file. When I view these emissions inputs in ncdump it appears to have the exact same format as the benchmark gridded emission file used by CMAQ, however when I run CCTM I get the following error:
Error reading IDs for variable AACD ACE
netCDF error number -49 processing file “GR_EMIS_001”
NetCDF: Variable not found
From reading this post, on the forum (Error creating GRIDMASK) it seems that I cannot create a CMAQ input from only NetCDF functions, and I have to use some I/O API tools also.
Since I now have gridded hourly emissions for each model species I don’t need to do temporal or species profiling.
Can anyone suggest the most efficient way to convert these emissiosns files into the format needed for CMAQ? Could I sure the Spatial-Allocator or m3tools perhaps? I have attached the output from ncdump -h my netcdf emissions input file.
