Integration of Ground-Based and Satellite Observations for the Analysis of Aerosol Mixed Effects and Radiative Forcing in Southeastern Asia

Project Details


In regard to this significant topic, the impacts of climate change, radiative forcing of anthropogenicaerosols, natural drivers and aerosol-cloud interactions are discussed by the IPCC AR5. In particular, theman-made components of aerosols are increasing with industry growth. Since different aerosol types exhibitdifferent absorption and scattering properties which can affect the solar incoming and outgoing radiance, theimpacts on radiative forcing at the surface and the top of atmosphere will lead to changes of radiative budget,rainfall pattern and global climate. The previous studies indicate that it’s necessary to consider aerosolparameters in atmospheric and climate models to retrieve more reasonable and accurate results. However, theimpacts of aerosol forcing are quite complicated and the estimation is sufficiently large uncertainty at present.That is why provide more accurate aerosol retrievals is one important part of this research. The aerosols willmix with the ambient aerosol and change its optical property easily and frequently during the pathway oflong-range transport. Mixtures of aerosols do not only lead the retrieval errors but also induce the uncertaintyof radiation energy estimation in atmospheric and climate models. As a result, it’s essential to provide properaerosol optical properties, especially under the mixing aerosols circumstances. The preliminary results of theaerosol discrimination and the aerosol mixing effect are shown on the previous phase of this research.Accordingly, the main aim of this study is to figure out the difference of aerosol optical properties aftermixing procedure and the changes of aerosol radiative forcing, including the development of models foraerosol types, optical properties and air quality monitoring with satellite observations and ground basedmeasurements in Southeast Asia.During the first year, the model of aerosol type discrimination method will be optimized, as well as themodel of three type included (dust, soot and sulfate) to retrieve more accuracy aerosol properties which canbe applied a wide world of air quality monitor (PM2.5). Then the radiative forcing of aerosols and mixtureswill be characterized in temporal and spatial distributions over South and East Asia. In the last year, theintegration of ground-based and satellite retrievals of aerosol type, mixed effects, PM2.5 and radiativeforcing will provide for the applications to the models related to regional air quality monitor andforecast, as well as the impacts on climate changes.
