Short summary

With observations from NASA's Multi-Angle Imaging Spectroradiometer (MISR) satellite instrument, we can constrain wildfire plume heights, smoke age, and particle size, shape, and light-absorption properties. We study over 3600 wildfire plumes across Siberia by statistically comparing the MISR results to observations of fire strength, land cover type, and meteorology. We then stratify plumes by land cover type and infer the dominant aerosol aging mechanisms among different plume types.
