Lauren C Andrews

Dr. Andrews is a glaciologist with the Global Modeling and Assimilation Office (GMAO) at NASA Goddard Space Flight Center (GSFC). Her research focuses on understanding the role of the cryosphere in the Earth system, including how glacial meltwater can alter the dynamic response of ice sheets and glaciers and how the representation of cryospheric processes, including snow and sea ice, can impact seasonal forecasting and climate projections. Dr. Andrews leads the PolarMERRA Reanalysis Project, a joint effort between GMAO and GSFC Cryospheric Sciences Laboratory, to produce a polar-focused, high-resolution atmospheric reanalysis and is a Deputy PI of Snow4Flow, a NASA Earth Ventures Suborbital-4 mission designed to measure, model, and project Northern Hemisphere ice mass and mass change.
