Development of 3-D Aerosol Distribution with Satellite Retrieval for the Application to Air Quality Monitoring and Model Forecast

Project Details

Description

The air pollution in Asia and Africa is the top issue in the world, which significantly impact on human health and environment/climate in regional and global scale. In particular, the man-made components of aerosols are increasing with industry growth in Asia. Since different aerosol types exhibit different absorption and scattering properties which can affect the solar incoming and outgoing radiance, the impacts 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 essential to consider aerosol parameters in atmospheric and climate models to retrieve more reasonable and accurate results. The investigation of aerosol source regions and pathway thus important to eliminate/prevent the severe air pollution in Asia. The construction of a real time monitoring and forecasting/warming system for a wide region air quality is urgently needed. Therefore, this research aims at the developing of the integration of satellite and ground based observations to fit the requirements of monitoring and forecasting/warming system in air quality, including (1) mapping aerosol vertical distribution with data from Micro Pulse Lidar (MPL) in first year of this project, (2) aerosol data assimilation association with aerosol vertical distribution, so base on aerosol partition to convert AOD to PM2.5 during the second year, and (3) the examination and construction of the near real time monitoring during the third year and (4) forecasting/warming system for air quality in Asia based on WRF-chem model with data assimilating in the last year.
