Research Interests
Observing System Simulation Experiments for Atmospheric Composition and Ocean Biogeochemistry
Building radiative transfer applications to run on NASA’s high performance computing cluster that simulate the sampling and spectral characteristics of future satellites missions. The software generates high resolution and time resolved synthetic top of the atmosphere radiances for UV-Vis remote sensing instruments. The data product is being used in Observing System Simulation Experiments (OSSEs) by scientists to prototype retrieval algorithms for upcoming satellite missions. The software has been applied to TEMPO, GOES, PACE, and the AOS constellation.
Global Aerosol Modeling and Data Assimilation
Development of global aerosol models and applications of satellite measurements in such models for air-quality forecasting, historical reanalyses, and observing system simulations in support of future NASA space missions. Curtent activities include analysis of the representation of aerosol optical properties in the GEOS earth system model, and use of machine learning algorithms for the assimilation of aerosol observations.
