Carbonaceous aerosol lab conducts carbonaceous aerosol research on its physical, chemical and optical characteristics via the observation system of carbonaceous aerosol, the basic analytical method, re-building the record and numerical simulation. It also commenced lab analysis of the basic characteristics, atmospheric chemical process of, and climatic effects of aerosol as well as the influence on environment and human health.
The lab conducts the aerosol monitoring programs in 14 different cities to obtain the special distribution data through employing thermo-optical analysis technique. Also the lab introduces the black carbon trace method into the calculation of secondary aerosol concentration and develops carbonaceous aerosol source apportionment by utilizing 8 different temperature stages for vaporizing organic and elemental carbon compounds. Furthermore, the lab is the pioneer to employ the thermo optical reflection method in analyzing the earth samples, therefore to achieve the combination of aerosol and earth deposition analysis. The thermo-optical method becomes the most effective way to distinguish the carbon in char and soot. By employing this approach, the lab re-established the atmospheric black carbon history record for Southern Asia and eastern China in the past 50-150 years. Moreover, the lab developed WRF-BC model specifically for black carbon atmospheric chemistry modeling. This model has been applied in many research fields, including black carbon sources, distribution and transportation. The scientists in the lab also try to gain more understanding of secondary carbonaceous aerosol mechanism by applying CMAQ model. Currently, the lab possesses an integrated numerical simulation system, analyzers for physical, chemical and optical characteristics and the online analyzers with high-precision.
