Research

Prof. Yang and his group are interested in the following research areas: 1) remote sensing of cloud and aerosol radiative and microphysical properties from satellite observations; 2) assessments of cloud and aerosol radiative forcing effects based on modeling capabilities and measurements; 3) scalar and polarized modeling capabilities for radiant energy transfer in the atmosphere-land-ocean coupled system; 4) theory and numerical capabilities for computing the optical properties of nonspherical and inhomogeneous particles and relevant applications to the studies of ice clouds, dust aerosol, and oceanic particles; 5) surface snow; and 6) applications of light scattering and radiative transfer capabilities to astrophysical problems such as interstellar dust.

Prof. Yang’s research group has been using the observations made by the Moderate Resolution Imaging Spectroradiometer (MODIS), the Clouds and the Earth's Radiant Energy System (CERES), the Atmospheric Infrared Sounder (AIRS), the Polarization and Directionality of the Earth’s Reflectances (POLDER), and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) instruments for various problems involved in atmospheric and oceanic remote sensing.

Because understanding of the radiative budget of the Earth-Atmosphere system must begin with the fundamental scattering and absorption properties of cloud and aerosol particles, the group makes significant efforts to simulate the optical properties of various nonspherical aerosol particles and ice crystals within cirrus clouds. The group has developed state-of-the-science light scattering computational capabilities summarized in an invited paper by Yang et al., 2019: On the convergence of numerical computations for both exact and approximate solutions for electromagnetic scattering by nonspherical dielectric particles, Progress In Electromagnetics Research, 164, 27-61. In addition, the group has developed databases (in particular, TAMUice2013, TAMUice2016, a tri-axial ellipsoidal mineral dust optical property database, and TAMUdust2020) of the optical properties of ice crystals and dust particles, which are extensively used by many other researchers worldwide. In particular, the MODIS, CERES, AIRS, and IIR (Imaging Infrared Radiometer) operational ice cloud retrieval products use the single-scattering properties of ice crystals developed by Prof. Yang’s group.

To implement advanced remote sensing techniques, fast radiative transfer models are often required. A substantial portion of the group's research effort is concentrated on developing fast models for the transfer of solar and infrared radiation under cloudy and aerosol-dusty conditions for passive remote sensing applications and an efficient Monte Carlo radiative transfer model for active remote sensing applications. In addition, the group has been working on vector radiative transfer to explore the application of polarization properties for atmospheric and oceanic remote sensing.

Recently, Prof. Yang’s group is interested in improving broadband radiative transfer submodels involved in climate models. For example, we found that the global average longwave scattering effect of clouds is comparable to the direct radiative effect due to doubling CO2. The group has also improved the ocean surface albedo model. Furthermore, the group has been studying 3-D radiative transfer.
