Creating "tot" output for domains outside the U.S

CMAQ Ancillary Inputs

I’m attempting to use inline dust emissions for a domain outside of the U.S. For this, a DUST_LU_1 and DUST_LU_2 file are needed. I am able to use GRIDCRO2D for the DUST_LU_1 (or can use the spatial allocator to create MODIS LU/LC types, then map to USGS types), but I’m unsure what is supposed to be in the DUST_LU_2 file. The documentation says it is the “tot” file and should contain the variable “FOREST”. I’ve tried using the benchmark data to discern how the USGS types are summed to create the “tot” file, but it is not clear. Any help is greatly appreciated - Thanks.

@cgnolte, do you know how this user can create DUST emissions for outside of the US?

Hi @lizadams and @cgnolte. -I was able to use the GRIDCRO files for dust emissions. Thanks.

how did you create the FOREST variable, please tell us?

I did not end up creating it - I just used GRIDCRO2D files for LU_1 and LU_2 and chose CTM_WBDUST_BELD=MODIS

oh, got it. Thanks for the quick reply.

I am having issue with convert_beld3_64bits.csh generated _tot file, which no one has replied yet (DUST_LU_2 file FOREST variable not correct).
