The emission data we use in our CMAQ simulation has 6 layers in the vertical direction (all near-surface); we need the WRF to provide the meteorological conditions of these six layers; In our old version (CMAQv5.2.1) we could extract these layers in CMAQ but in the newer version of the CMAQ (CMAQ5.4…

There were some significant changes made to how emissions data were processed in version 5.3, including the Detailed Emissions Scaling, Isolation, and Diagnostics (DESID) module and the Centralized Input/Output (CIO) module. These are described in the [release notes].( CMAQ/DOCS/Release_Notes/README.…

Thanks for your response so much! In CMAQv5.2.1, I can set or extract the vertical layers(or called layer collapsing cuz we only need to use the near-surface six layers of WRF outcome) in MCIP, like the following (run_mcip.csh) set CTMLAYS = “1.000, 0.993, 0.983, 0.97, 0.954, 0.934, 0” But in CMA…
