Brief Bio


As a research scientist within Deep Blue Aerosol Group at NASA's Goddard Space Flight Center, Dr. Jaehwa Lee's research focuses on developing aerosol retrieval algorithms for passive satellite sensors in both LEO and GEO to provide the scientific community with better aerosol data sets to work with. His recent work at Goddard includes improving aerosol optical property models in the Deep Blue aerosol algorithms particularly for nonspherical mineral dust aerosols, retrieving aerosol layer height synergistically using multiple passive satellite sensors, and extending aerosol data coverage to the areas covered by thin cirrus clouds.

Research Interests


Satellite remote sensing of aerosol optical properties

Earth Science: Aerosols

Dr. Lee's research focuses on the development of aerosol remote sensing algorithms for passive satellite sensors making measurements from UV to IR wavelength range, to better understand aerosols' role in the Earth system. His recent work at Goddard includes improving aerosol optical property models in the Deep Blue aerosol algorithms particularly for nonspherical mineral dust aerosols, retrieving aerosol layer height synergistically using multiple passive satellite sensors, and extending aerosol data coverage to the areas covered by thin cirrus clouds.
