From: Australia’s Black Summer pyrocumulonimbus super outbreak reveals potential for increasingly extreme stratospheric smoke events

Fig. 7

Top panel shows profiles of 532 nm attenuated backscatter (km−1 sr−1) observed by CALIOP on 02 January 2020 for a daytime (ascending) CALIPSO overpass beginning 01:37 UTC. Dashed white lines denote the approximate upper and lower bounds of the plume. Bottom panel shows near-coincident ultra-violet aerosol index (UVAI) observations from OMPS. The CALIPSO satellite track is superimposed green, with black indicating the segment used in the top panel. The horizontal extent of the stratospheric smoke plume (AI ≥ 15) is displayed in shades of yellow and red.
