Will try out, thanks for the suggestion.jordanschnell said:ndepvel looks to be an integer that describes how many species deposition velocities (depvel) will be calculated for. I don't quite understand the reason for the error/catch of ndepvel vs. num_vert_mix. My advice would be once you find out what number you need for ndepvel (either numgas or numchem), try a value that's much larger than what you need to see if your results change.

@neel14 - to answer your previous question - the difference between the ACM scheme and others is that vertical mixing of chemical species (and deposition) is done inside the ACM pbl scheme. For other pbl schemes, vertical mixing is done in the dry deposition driver by using exchange coefficients diagnosed in the PBL scheme used. num_vert_mix is set to num_chem so the ACM scheme knows how many species to loop over. If num_vert_mix is anything except for zero, mixing and deposition is not performed in the dry_dep_driver.F (that way it's not done twice).
@mriganka - The 201 chemistry option is a very big package, with what looks to have 208 species. Because ndepvel has a default value of 140, the error occurs in chemics_init.F. To remedy, you need to set ndepvel = num_chem in the &chem namelist, which should be 208.
