FireWx Integration of the Freitas 1-D Model with NUCAPS for Assessing 2020 California Pyrocumulonimbus Events

We integrate the Freitas 1-D plume rise model (FPRM) with the NOAA Unique Combined Atmospheric Processing System (NUCAPS) to improve profiling of the thermodynamic environment of pyroCumulonimbus (pyroCb) events observed in California during 2020. NUCAPS has been applied by the Naval Research Laboratory – Marine Meteorology Division to derive inputs for a prototype pyroCb prediction model. Although results are still preliminary, NUCAPS does show skill in assessing the vertical profiling of pre-convective conditions leading to the occurrence of pyroCb activity. FPRM has been widely used in environmental impact assessments, particularly in scenarios involving industrial emissions, prescribed burns, and wildfires. It remains a valuable tool in atmospheric science and environmental management, offering reliable smoke transport predictions for emergency response planning, regulatory compliance, and scientific research. We will assess the performance of NUCAPS as a direct input to the FPRM model. Additionally, by applying FPRM, we intend to improve the understanding the dynamics and impacts associated with pyroCb events.
