Profile
My research has been focused on the simulation of air pollution from various natural and anthropogenic sources. Currently, I am working on improving fire weather and atmospheric composition prediction capabilities in atmospheric models and applying these tools to understand and forecast various processes associated with fire weather and smoke. These processes include wildland fire emissions and plume rise, smoke transport and mixing, smoke chemistry, the impact of smoke on radiation and microphysics, and so on. I have been working with coupled meteorology-chemistry models (e.g. WRF-Chem). One of the coupled weather-smoke models developed by our team, HRRR-Smoke (https://rapidrefresh.noaa.gov/hrrr/HRRRsmoke/) has been operational at NCEP since 2020. In collaboration with other teams, we are currently developing NOAA's next-generation high-resolution smoke and dust forecasting model RRFS-Smoke-Dust (https://rapidrefresh.noaa.gov/RRFS-SD/).
