Land surface model (Simplified Simple Biosphere Model, SSiB) development, including biophysical processes, photosynthesis process, cryospheric processes, and dynamic vegetation processes.
Atmosphere-land surface coupling processes and hydrometeorological prediction, focusing on the impact of land-surface processes, including vegetation biophysical processes, land-cover and land use change, and land-surface parameters and parameterizations, on regional climate and global climate variability and anomalies, with a special emphasis on monsoon systems, and the mechanism involved.
Leading an effort for the GEWEX/GASS Initiative “Impact of initialized land temperature and snowpack on sub-seasonal to seasonal prediction (LS4P)”
Leading an effort for the NSF Ea EM-3: Surface-induced forcing and decadal variability and change of the East Asian climate, surface hydrology & agriculture–A modeling and data approach.
Leading an effort for West African Monsoon Modeling and Evaluation (WAMME).
Land surface & East Asian drought/flood (NSF-project-Summary).
Regional climate downscaling
Remote sensing methodology for atmospheric and land surface variables, and application of remote sensing products in prediction studies.
Relations between environment and climate conditions and different genetic strains of malarial mosquitoes.
Areas of active research include East Asia, West Africa, Continental U.S., and South America.
