Abstract:
The summer 2020 Australian fire season resulted in several large-scale smoke plumes transported across the continent and southern Pacific Ocean between November 2019 and February 2020. Satellite retrievals of quantities such as aerosol optical depth (AOD) are used widely to constrain and evaluate climate models. However these retrievals are challenged by extreme events, where retrieval assumptions may be violated, and observability issues affect their representation in data aggregates (e.g. monthly means). We compare satellite sampling and retrievals of AOD (as well as retrieved or implied absorption AOD) during this fire season, and discuss the implications for our abilities to constrain aerosol loading and absorption from space during such events.
