Wildfire smoke is a radiatively important source of aerosols historically and is growing in importance with changing climate. Satellite-based remote sensing instruments are a powerful tool to that allows the near continuous measurement of these important emitters that can be located in remote regions. However, converting the satellite measurements (e.g. radiance) into useful aerosol parameters (e.g. PM2.5) sometimes require assumptions about the aerosol microphysical and optical properties. In this work we present in situ measurements of the optical and microphysical properties of smoke measured during airborne campaigns in North America since 2019 including FIREX-AQ, AEROMMA, and PACE-PAX. These campaigns measured fresh and aged wildfire smoke from the western United States and Canada. Besides typical measurements of aerosol size distributions, we also measure the aerosol scattering phase function which allows for aerosol property retrievals using the GRASP (Generalized Retrieval of Atmosphere and Surface Properties) algorithm. We will present the retrieved parameters (e.g. particle mode diameter, real refractive index, etc.) and evaluate them against other in situ measurements.
