I'm running GEOS-Chem driven by GCAP2.0.

As we know that the OFFLINE Natural Emissions (e.g., Dust, BiogenicVOC, Seasalt, etc) are now available for the native meteorological fields at resolutions of MERRA-2 and GEOS-FP. Also, the default behavior for GCAP 2.0 is to use online calculations to respond to the underlying climate for natural emission.

However, I would like to design my own simulation. >> I am now re-gridding offline natural emissions to a 2x2.5 degree resolution to match the GCAP2.0 meteorological field. Then, I set up my experiment using;

• GCClassic: v14.4.3
  - Full Chemistry
  - Turn off ONLINE natural emission and Turn on OFFLINE natural emission (fixed to year 2015).

But I found that there is an error with dust_emissions_20.20150101.nc - Cannot get field EMIS_DST1. (attached GC_1.txt)

My question is : "Is it possible to run GEOS-Chem driven by GCAP2.0 with OFFLINE natural emissions"

I am looking forward to your constructive feedbacks. Thank you very much.
