Hi, recently while going through the CMIP6 output I came across these 2 table ids. I dont quite understand what is the difference between them, although I have looked them up in the relevant documents. It just says Amon is atmospheric monthly data whereas Aermon is atmospheric chemistry and aerosol monthly data. If someone could describe it in a little more detail, that would be helpful. Thanks.
Hi, thanks for the reply. So, is there any difference in the model configuration or anything, e.g., aermon is run with a more comprehensive atmospheric chemistry and aerosol scheme while amon is not? And what would be the difference in the two tables for the same variable, e.g., 'ua' in amon vs aermon? Or can you just point me to documents/resources which have info about this in more detail? Thanks!
There were no changes in model configuration for data that's in Amon vs AERmon. The "ua" field in AERmon is the original "U" data from CESM; in Amon the "ua" data are "U" but interpolated to a set of pressure levels. AERmon was a new table in CMIP6 compared to CMIP5 and was designed to meet the needs of AerChemMIP.
There's a GMD paper on the CMIP6 data request at
The CMIP6 Data Request (DREQ, version 01.00.31)
Abstract. The data request of the Coupled Model Intercomparison Project Phase 6 (CMIP6) defines all the quantities from CMIP6 simulations that should be archived. This includes both quantities of general interest needed from most of the CMIP6-endorsed model intercomparison projects (MIPs) and...
as a good starting point.
