Curriculum Vitae:

Sun Wong

My research interests are mainly on analyses of climate and weather processes using both satellite-based observations and models. My research covers many topics that include Saharan dust transport and radiative effect, water and energy balances in the atmosphere, variability of Indian summer monsoon, tropopause variability, stratospheric and tropospheric chemistry, and connection among clouds, precipitation and large-scale dynamical systems. I am a scientist at the JPL Atmospheric Physics and Weather group and responsible for validation of AIRS temperature and specific humidity retrievals against radiosonde measurements.
