Greetings,
I intend assess climate change effects on air quality.
In order to capture small scale effects as topograhy and land use (dynamical downscaling), i will use the WRF model to reducing spacial resolution and coupling CMAQ to solve atmospheric transport and chemistry.
However, firstly, i need to couple Global Climate Model Output in WRF input (WPS).
I have seached by models that integrating last IPCC experiment (CMIP6), but i realize that models output is focus on validation Climate Models and not to regionalization effort (lacking data).
I have read some works that assessed USA climate change effects on air quality using CESM1 model because was avaliable format intermediate files to WRF (CISL RDA: NCAR CESM Global Bias-Corrected CMIP5 Output to Support WRF/MPAS Research).
I accessed CMIP5 repository (https://esgf-node.llnl.gov/search/cmip5/) and do not find CESM1 model output, but i found information that CESM1 = CMIP5 CCSM4 Model (CESM 1.0 Experiments, Data and Diagnostics).
Can you answer some dubts?

Can you answer some dubts?
- Is CESM1 model a CMIP5 model member?
- Is CMIP6 CESM2 model is a updatting of CESM1?
- Do you intend became avaliable format intermediate files to inicialization WRF, as did to CESM1 (CISL RDA: NCAR CESM Global Bias-Corrected CMIP5 Output to Support WRF/MPAS Research)? In negative case, is it possible became avaliable all parameters to create a format “grib” file and insert in WPS (table below)?
