plementation of Atmospheric Correction (MAIAC) algorithm at 1 km resolution. Keypoints: • Remote sensing multi-angular, polarimetric observations are shown to be sensitive to the amount of black carbon in a wildfire smoke plume through comparisons with in situ airborne measurements; • Radiative closure was achieved and demonstrated the ability to constrain the black carbon mass fraction to approximately 5%, assuming external mixing of chemical components from landscape fires. This, however,

State-of-the-art airborne remote sensing instruments, such as imaging polarimeters, could potentially contribute to such efforts by generating highresolution aerosol property information over smoke-affected areas.
