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. Table 1. Summary of scenarios setting in three coupled models. Model Scenario Configuration option Description WRF-CMAQ (1) WRF-CMAQ_NO DO_SW_CAL=F Without aerosol feedbacks (2) WRF-CMAQ_ARI DO_SW_CAL=T ARI WRF-Chem (3) WRF-Chem_NO aer_ra_feedback=0 wetscav_onoff=0 cldchem_onoff=0 Without aerosol feedbacks (4) WRF-Chem_ARI aer_ra_feedback=1 wetscav_onoff=0 cldchem_onoff=0 ARI (5) WRF-Chem_BOTH aer_ra_feedback=1 wetscav_onoff=1 cldchem_onoff=1 ARI and ACI WRF-CHIMERE (6) WRF-CHIMERE_NO direct_feed_chimere=0 indirect_feed_chimere=0 Without aerosol feedbacks (7) WRF-CHIMERE_ARI direct_feed_chimere=1 indirect_feed_chimere=0 ARI (8) WRF-CHIMERE_BOTH direct_feed_chimere=1 indirect_feed_chimere=1 ARI and ACI 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. Table 2. Model configurations and parameterization schemes.
