วัตถุประสงค์
:
1. We will collect 6 lake sediment cores in different climatic zones and reconstruct the wildfire history including both flaming and smoldering combustion in the Asia in the middle- and low-latitude Asian regions covering the past 2000 years. The relationship among the climatic zones, vegetation types, the combustion types, and carbonaceous aerosol emissions from biomass burning will be put forward.
2. We will find out the transport and evolution characteristics of black carbon; obtain the particle size distribution, mixing state, optical property, and hygroscopic characteristics of black carbon at a high time resolution scale; and establish the connection between aerosol radioactive forcing and these characteristics of black carbon mentioned above.
3. Using the WRF-Chem model, we will find out the radiative effects of carbonaceous aerosol emitted from biomass burning in the middle- and low-latitude Asian regions; discuss its influence on monsoon precipitation, and forecast the trend of biomass burning, its emissions and their direct and indirect climate effects in the next 30 years.
