Source codes of WRF v4.1.1-CMAQ v5.3.1, WRF-Chem v4.1.1 and WRF v3.7.1-CHIMERE v2020r1
Description
Here presented all related source codes for the two-way coupled WRF-CMAQ, WRF-Chem and WRF-CHIMERE models, and the pre- and post-processing scripts used for the paper of "Inter-comparison of multiple two-way coupled meteorology and air quality models (WRF v4.1.1-CMAQ v5.3.1, WRF-Chem v4.1.1 and WRF v3.7.1-CHIMERE v2020r1) in eastern China". We investigate the performance of each coupled model over eastern China during 2017, and related configurations of each coupled model regarding aerosol-radiation interactions (ARI) and/or aerosol-cloud interactions (ACI) effects as presented in the following Table1.

More detailed information on model configuration of WRF-CMAQ, WRF-Chem and WRF-CHIMERE are in 201701icbc.csh, namelist.input and chimere.par files, respectively. Table 2 lists several configurations of these three coupled models, as follows.
