CESM1(+) preprocessor for simple box model validations of chemistry


New Member
CHEM PREPROCESSOR was available 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. Could you please provide some links describing how new chemistry can be studied using a simple 0 or 1 dimensional box model for typical upper atmosphere cases used for testing chemistry? Where typical cases are distributed as input .nc-files for a box model or, perhaps, CESM simpler models to test chemistry?

Hi Olexandr,

I am moving this post to the CAM-Chem forum, as the people who watch that particular forum will be the most likely group to have the answer(s) you need.

Hope that helps, and have a great day!
