Hi All,

I previously managed to run CMAQ-DDM for the older version of CMAQ. It was able to calculate the sensitivities for whole layers so that I could calculate the sensitivity of columns to relevant emissions. However, oddly, the new version (CMAQ-DDM 5.2) only outputs the surface layer. Is there any option to include all layers or a modification that should be made inside of scripts?

Thanks!

Amir

Yes, you can write out all of the layers you want. Currently, the sensitivities are written out for the same layers as average concentrations.
