Abstract. The acidity of atmospheric particulate matter regulates its mass, composition, and toxicity has important consequences for public health, ecosystems climate. Despite these broad impacts, the global distribution evolution aerosol particle are unknown. We used comprehensive multiphase chemistry–climate model EMAC (ECHAM5/MESSy Atmospheric Chemistry) to investigate main factors that cont...

The hydroclimate of the Tibetan Plateau (TP) and Central Asia (CA) plays a crucial role in sustaining surface water reservoirs thus resources respective regions. In this study, we investigate changes Asian its driving forces during specific time intervals last 3 Ma. We conduct high-resolution (∼0.75° per grid cell) general circulation model ECHAM-5 experiments with boundary conditions for mid-P...
