My work focuses on the development of complex coupled modeling systems to simulate atmospheric composition, air quality, weather and their interactions. I am one of the primary developers for
Scientific development of the next generation global aerosol forecast model within the Unified Forecast System (UFS-Aerosols).
The development of the operational global aerosol prediction of the Global Ensemble Forecast System (GEFS-aerosols), in NECP operation since September 2020.
The inclusion of the direct and semi-direct aerosol feedbacks in GSL’s version of GEFS-aerosols that uses the Common Community Physics Package (CCPP) for coupling.
The development of GSL’s FIM-Chem model, which includes simple and complex atmospheric composition modules from WRF-Chem (FIM-Chem was used to provide aerosol optical properties to the Air Force Weather Agency averaged over 10 years of forecasts).
I contribute to the development of the Community Multiscale Air Quality (CMAQ) model as it is coupled with FV3GFS (global and regional) for air quality prediction studies; additionally, I work on atmospheric composition model evaluation, aerosol feedback studies related to S2S forecast, and aerosol data assimilation. I am experienced using WRF-Chem, GEOS-Chem, and the GEOS-Chem adjoint. I assisted the Unified Forecast System (UFS) community through my part in developing workflows and UPP by implementing chemical model related parts.
