    Sampa Das is an ESSIC/UMD research scientist at the NASA GSFC Atmospheric Chemistry and Dynamics Laboratory (code 614). She obtained her Ph.D. in Atmospheric Sciences from Purdue University in 2018. Her dissertation work involved, (1) assessing the simulations of long-range transport and vertical distribution of southern African biomass burning aerosols in multiple global atmospheric models and (2) quantifying the impact of transported aerosols on stratocumulus clouds and regional energy budget using NASA GEOS (Goddard Earth Observing System) model. Following her Ph.D., she joined GSFC as a NASA Postdoctoral Fellow. Here, she continues to utilize her experience in global aerosol modeling to diagnose and improve the representation of aerosol-related processes and properties in the GEOS Earth System model using observations from a combination of satellites, aircraft, and ground-based instruments.
