Decadal application of WRF/chem for regional air quality and climate modeling over the U.S. under the representative concentration pathways scenarios. Part 2: Current vs. future simulations
WRF/Chem under RCP scenarios predicts similar domain-mean increases for 2-m temperature but different spatial distributions. Future O3 levels will increase for RCP8.5 scenario due to higher GHGs and BVOCs and dis-benefit of reduced NOx in some areas. Future PM2.5 levels decrease under RCP4.5 and RCP8.5, causing lower cloud droplet number concentration and higher radiation.
