GHG file for extended FHIST through year 2015

Hi,

I'm running a FHIST run from year 1995 to year 2014 with cam5. And I need the GHG forcing file (bndtvghg in cam user namelist) that goes to year 2014.

The default GHG file the module selected is "/glade/campaign/cesm/cesmdata/inputdata/atm/cam/ggas/ghg_hist_1765-2005_c091218.nc", which only goes to year 2005. I also found a new one under the same directory: "ghg_hist_1750-2014_0p5_CMIP6_c170823.nc". However, the new file has monthly data depending on coordinates of time and latitude, while the default file has yearly data depending only on time. I tried to do annual and latitudinal (weighted) averages to the new file, and it turned out the results didn't match with the default files when I compared the values in the same year.

If I directly put the new file into the simulation, the error messages are:
Code:
 ghg_ramp_read         409
 NetCDF: Start+count exceeds dimension bound

 ERROR: HANDLE_NCERR

I wonder if is there any existing GHG-forcing file that goes into year 2014. Or is there any specific way to make the new file have the same format and data as the default file?

Thanks,
Yi
