Adding Particle Photochemistry to Atmospheric Chemical Models

_{Using our measurements from the ALPACA field campaign, we added particle-phase brown carbon photochemistry to the Platform for Atmospheric Chemistry and Transport in One Dimension (PACT-1D) model to understand how particle photooxidants contribute to the formation of PM pollution. This project specifically focuses on the formation of secondary sulfate and secondary organic aerosol during severe winter pollution events in Fairbanks, Alaska.}

Alaskan Layered Pollution And Chemical Analysis (ALPACA) Field Campaign

_{The ALPACA field campaign was a six-week field campaign in Fairbanks, Alaska in January and February 2022. The goals was to understand the driving forces behind the severe pollution episodes that overwhelm Fairbanks each winter, a phenomenon common in high-latitude cities across the world. My contribution was to characterize the production of particle-phase photooxidants and explore their contribution to multiphase chemical processing of the brown-carbon rich PM pollution in Fairbanks.}
