    Dr. Aish Raman is a Senior Research Scientist working on aerosol modeling. At NASA GSFC, she works on marine aerosol modeling using a wave model. She received a B.E (2011) in Geoinformatics from College of Engineering, Anna University, India and a M.S (2013) and Ph.D. (2017) in Atmospheric Sciences from the University of Arizona. Her primary research interests include satellite remote sensing, modeling, and assimilation. Dr.Raman is interested in using these tools to understand the processes governing aerosol distribution in space and time. At GMAO, she focuses on implementing parameterizations for marine aerosol emissions in GEOS using wind wave characteristics.

    Dr.Raman's Ph.D research focused on developing constraints for aerosol distribution using multi-satellite, multispectral remote sensing datasets, ground measurements, radar, and a chemical transport model. In particular, her research focused on dust and black carbon aerosols. During her doctoral research, she co-authored a NOAA NWS technical memorandum on blowing dust and contributed chapters related to high resolution WRF-Chem modeling framework for convective dust storms (haboobs) in Arizona. In addition, Dr.Raman also worked on several modeling projects to study interstate transport of Carbon monoxide (CO) and Black Carbon (BC) pollution using tagged tracers. She also worked at NCAR as a graduate student visitor during the summer of 2016. While at NCAR, she worked on improving aerosol forecasts from the WRF-Chem model by combining satellite aerosol retrievals with the model in an analog ensemble framework.

    Dr. Raman also worked on planetary remote sensing data analysis for Mars at Indian Space Research Organization as a student intern during B.E. Her research focused on analysis of spectroscopic properties of Martian minerals and polar ice caps using the data from Mars Reconnaissance Orbiter. She also collaborated with Indian Institute of Astrophysics in Bangalore to work on cloud optical properties in Venus using the telescopic observations.
