Work Package 4

Regional model improvement and evaluation for quantifying multiscale impacts of non-CO2 forcers

ESMs from WP3 will provide boundary conditions to test the impact of the process improvements on regional scales, with the focus on Europe and for other targeted regions (Africa, Latin America and South Asia). Regional modelling approaches will be refined in WP4, which will bring together key regional scale climate and atmospheric composition models (RegCM, WRF-Chem and WRF/CMAQ) that will be driven by output from existing CMIP6 global ESMs and deliver significantly higher resolution outputs. The regional models will be evaluated for Europe and other selected regions with boundary conditions from WP3 and derived from CMIP6.
