Abstract: In this article, we compare two California wildfires during the COVID-19 pandemic and determine the extent to which environmental characteristics affect the diffusion of wildfire smoke. We model the spread of smoke concentration in the region of the fires using a diffusion-advection-decay equation considering existing particulate matter as a source. We derive the coefficients for the model from Boltzmann calculations, wind speeds, and half-life. We analyze the resulting solution curves and numerical data through a MATLAB program to suggest reforms, modifications, and addenda to policies on the evacuation and return of affected residents. We find return policies can be modified so residents return 2 weeks before or after the recommended time, which we concluded as 3 months after initial ignition.
