Professional Biography

Aish Raman is a research scientist at the Bay Area Environmental Research Institute (BAERI) and NASA Earth Exchange (NEX) at Ames Research Center. Dr. Raman works on the TRACER project, focusing on chemical data assimilation using WRF-Chem/DART to advance the development of regional reanalysis for atmospheric constituents. Aish Raman is particularly enthusiastic about exploring the impact of both geostationary (GEO) and low Earth orbit (LEO) satellites on improving model predictability for extreme air quality events like wildfires and dust storms.

Prior to joining NASA Ames, Dr. Raman worked at the Pacific Northwest National Laboratory (PNNL), where she conducted research on modeling aerosol ice nucleating particles (INPs) and investigating the predictability of INP parameterizations for marine regions using a global climate model. 

Additionally, she is an accomplished pilot, fueling her enduring passion for aviation and the exhilarating experience of flying airplanes.
