Simulation of Future Air Pollution Changes Based on Global Model Comparison Program CMIP6 and Regional Climate-Chemistry Coupling Model WRF-Chem

The national carbon peak carbon neutrality (double carbon) goal puts forward new requirements for future air pollution control, and also puts forward uncertainties for the simulation and prediction of the evolution trend and spatial pattern of the atmospheric environment under the background of future climate changesex and challenges.Based on different shared socioeconomic pathways (SSPs) and the latest anthropogenic emission trends, the Sixth International Coupling Model Intercomparison Project (CMIP6) projected future climate change trends under different social sharing pathways and GHG emission scenarios. These results are as follows:It is possible to simulate and predict the evolution trend of air pollution under the background of future climate change.
Dynamic downscaling of the projected global climate data from the Model Comparison Program, combined with projected future climate change, using regional climate models and coupled climate-chemical models to predict and simulate the temporal and spatial evolution of air pollution in the future.The model comparison plan involves format conversion and downscaling of data, and regional models involve complex dynamic and chemical processes, which are difficult in data utilization and model operation.
