RESEARCH INTERESTS AND RESEARCH BACKGROUNDS IN DETAILS:

 

My research interest focuses on atmospheric radiation and radiation involved applications including 3-D radiative transfer modeling; diagnosis and prediction of the climate changes due to the natural and man-induced perturbations using satellite retrieved data and modeling; and retrieval of various atmospheric and surface parameters. My research experiences in atmospheric physics and atmospheric dynamics have led to and will strengthen these interests.

 

In the past several years, I improved the accuracy of the currently used adjacency model over a heterogeneous surface under hazy condition due to scattering of particles in the air. A theoretical model was derived from radiative transfer equations. Tanre’s surface adjacency model can be degraded from it for less accuracy. The improved model was demonstrated by applying to ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and MODIS (Moderate Resolution Imaging Spectroradiometer) surface reflectance retrieval in visible channels. This contributes to the first part of my PhD dissertation.

 

Atmospheric aerosol exerts impacts on climate changes by redistributing the solar energy through scattering and absorption processes, acting as cloud condensation nuclei (CCN), and participating in heterogeneous chemical reaction to depleting some atmospheric species. The aerosol indirect effect to climate was one of important research frontiers in recent years. In this circumstance, to accurately monitor aerosol sources and the transportation from space appears to be a very important issue. The retrieval of aerosol optical properties, especially aerosol optical thickness, is accurate over ocean and dense dark vegetation land surfaces, but not over the bright land surfaces. For example, MODIS aerosol retrieval algorithm over land is not applicable over a bright surface. Retrieval of aerosol properties over bright land surface from MODIS will benefit the scientific community considering the long continuity and broad coverage of MODIS even though MISR (Multi-angle Imaging SpectroRadiometer) provides retrieval over bright surfaces based on multiple angles scanning. Therefore, I developed an algorithm to retrieve aerosol optical properties over bright surface based on the “blurry effect” of atmospheric particles. At the present, the algorithm shows a reasonable agreement with AERONET(AErosol RObotic NETwork) ground measurement, but still must be further refined. This contributes to the second part of my PhD dissertation. 

 

I also have a solid background in atmospheric dynamics. During my undergraduate study, I majored in meteorology. After my study as a student in the Master program, I worked on the nonlinear stability of the atmospheric basic flow. The basic flow is defined as a stationary state, and the difference between an actual and a basic flow is viewed as a perturbation. Whether a perturbation will develop or decay is determined by the stability of the basic flow. This is a typical technique to study the evolution of the atmospheric fluid. I designed an algorithm to extract a basic flow optimally representing the corresponding actual flow, and studied the evolution of perturbations of different frequencies on the basic flows with different nonlinear instability.

 

Besides the research mentioned above, I have done research on aerosol sources and transportation from analyzing aerosol chemical composition. Aerosols from different sources display a special character in their chemical composition. Aerosols were sampled to analyze their chemical compositions, from which the information of aerosol sources and transportation was estimated by using statistical methods such as Factor Analysis (FA) in conjunction with other meteorological parameters. 

 

My future core interest is mainly in the general area of radiation, in particular the development/application of radiative transfer models, retrieval algorithms for atmospheric and surface parameters from space. I am also interested in pursuing research in the area of climate change, including the diagnosis and prediction of the various scale climate changes, such as aerosol-cloud interaction, global hydrological cycle, and the accompanying climate forcing.
