Research Interests

  • Atmospheric radiative transfer;
  • Light and electromagnetic scattering;
  • Atmospheric and oceanic remote sensing.

My research on radiative transfer and light scattering aims to improve the accuracy and efficiency of remote sensing and climate/weather modeling, and deepen our understanding of the atmosphere and terrestrial environment. I developed a vector radiative transfer model (VRTM) and associated Jacobian computational model for a coupled atmosphere-land-ocean system, in support of remote sensing using radiometric and polarimetric observations. I recently made a breakthrough in light scattering by spheroidal particles. I derived an analytical solution to optical properties of spheroids based on spheroidal coordinates. Compared with previous studies, my new formulation is much more numerically stable, and the maximum applicable particle size is extended by more than 30 times. My research also includes the study of optical and microphysical properties of ice clouds and dust aerosol employing satellite observations in visible, infrared and microwave bands. I am also interested in the applications of radiative transfer and light scattering techniques in other fields, such as planetary sciences and astronomy.
