Using VIIRS fire radiative power data to simulate biomass burning emissions, plume rise and smoke transport in a real-time air quality modeling system

In this presentation, we present a new smoke modeling system High Resolution Rapid Refresh (HRRR-Smoke) to simulate biomass burning (BB) emissions, plume rise and smoke transport in real time. The HRRR model (without smoke) is run as an operational numerical weather prediction system at the National Weather Service. HRRR is NOAA Earth System Research Laboratory's version of the Weather Research and Forecasting (WRF) model. Here we make use of WRF-Chem (the WRF model coupled with chemistry) and simulate fine particulate matter (smoke) emissions emitted by BB as well as anthropogenic sources. The model includes an aerosol aware double moment Thompson microphysics scheme [1], which allows to simulate smoke feedback on microphysics in a computationally efficient manner.
