1. Interests
· Chemical transport model
A 3-D global chemical transport model is an essential tool to examine the changes in chemical composition in the atmosphere here those consequences range from regional air pollution to global climate change
· Secondary organic aerosol
Organic aerosol (OA) constitutes significant mass fractions (20%-90%) of total dry fine aerosols in the atmosphere and has adverse effects on human health and atmospheric visibility. In particular, secondary organic aerosols (SOAs), which are produced in the atmosphere from gas-phase precursors, are poorly understood relative to primary organic aerosols (POAs), which are directly emitted from sources. Global models of OA have shown large discrepancies when compared to the observed values because of the limited capability to simulate SOA. Such simulations poorly represent complex SOA formation in the atmosphere
· Brown carbon
Many field observations and chamber studies recently showed that a certain fraction of OC could absorb solar radiation, especially for shortwave (below 400 nm) wavelengths. This light-absorbing OC fraction is referred to as brown carbon (BrC). If the BrC is prevalent and its climate effect is significant, then the previous estimates of climate effect need to be revised.
