CESM simpler models for testing new chemistry


New Member
CHEM PREPROCESSOR was available in WACCM-3 in 2009 being distributed as a .tar-file to run the preprocessor externally as it follows from the comment of D.Marsh at New species
Unfortunately, recent contributions and tutorials don't let suggesting that a preprocessor could be extracted from CESM to test new chemical rates and reactions using modest computational resources. Instead, a case should be created using a modified preprocessor input file and the whole CESM1(+) model should be built with new chemistry to test.
Which particular CESM simpler model is capable of testing new chemistry in the mesosphere and at higher altitudes? Could you please mention differences of studying new chemistry using a CESM full model and CESM simpler models? Where typical atmosphere cases used for testing chemistry are distributed as input .nc-files?
