   My group’s current research focuses on studying cloud properties and their impact on the surface and TOA energy balance from ground- and satellite-based remote sensing, understanding the important of cloud-radiation interactions and feedbacks to regional climate change, and improving climate model simulations using both surface and satellite observations. These research efforts have been supported by DOE Atmospheric Radiation Measurement (ARM) program; NASA Cloud and the Earth’s Radiant Energy System (CERES), Modeling, Analysis and Predication (MAP), Energy and Water Cycle Study (NEWS), and INTEX-B programs; NSF Atmospheric Sciences and Earth Sciences programs; and UND Faculty Seed Money.

• Retrieving cloud-radiation properties using ground-based remote sensing, providing statistical cloud-radiation information using long-term ground-based data for climate models.

• Validating satellite cloud-radiation results using ground-based data as a ground-truth, studying the radiation budgets at surface, TOA and Atmosphere using both surface and satellite observations.

• Evaluating the climate model simulations of cloud-radiation processes, and improving/developing cloud-radition parameterazition.

• Studying aerosol indirect effect on cloud microphysical properties, as well as aerosol-cloud-climate interactions in the middle and high latitudes.

• studying Asian Dust Events using NASA MODIS, EAST-AIRE and DC-8 in situ measurements during the INTEX-B field experiment.
