Summary:KDD’23 Fragile Earth Workshop; Long Beach, CA, USA; August 6-10, 2023 ... : This study investigates the impacts of the black carbon (BC) aerosols generated during the 2019 extreme Amazon wildfire events on the sea ice extent over the Antarctic region. Random forest (RF), elastic net regression (EL), matrix profile (MPF), and causal discovery (CD) analysis have been employed on a suite of satellite measurements for this analysis. In 2019, a higher number of BC aerosol atmospheric rivers (AAR) that transport the aerosols from the Amazon region arrived in the Antarctic region compared to 2018. It has been observed that between August 2019 and February 2020, SIE loss over the Antarctic region increased threefold (487 Gt) than the mean SIE loss (143 Gt per year) from 2002. The Weddell, Ross Sea (Ross), and Indian Ocean (IO) regions experienced higher loss in SIE during BC AAR days during that period, with the Weddell region topping the chart. Bell-Amundsen (BA) and the Pacific Ocean (PC) region were the least affected and showed the minimum and insignificantly different SIE loss as ...
