    Gregory Elsaesser's research focuses on the use of observations from multiple satellites (Aqua AIRS, GPM, TRMM) and NASA/DOE field campaigns to improve our understanding of convection and the environment in which it is developing. Knowledge gained is used to improve global climate model parameterizations. He also develops satellite algorithms for the retrieval of and creation of rain and cloud property records. Recent work includes development of the Multisensor Advanced Climatology of Liquid Water Path (MAC-LWP) record for improved cloud LWP observations in stratocumulus regimes and constraints on total LWP observations in deep convective regions, and improvement to the parameterization of ice and liquid in convective updrafts for use in the GISS Model E3 GCM.
