Fig. 1: Cloud property retrievals for the ice ring derived from the Advanced Himawari Imager (AHI; aboard the Himawari-8 satellite) at 05:17 UTC on 15 January 2022.

From: Transient ice ring observed during the 15 January 2022 eruption of Hunga volcano

Fig. 1

The circle annotated on each panel indicates a radial distance of 300 km from Hunga volcano (red triangle). a True colour image. b Brightness temperature difference (BTD) between the 8.6 and 11.2 μm AHI channels. c Cloud-top height. d Cloud effective radius. e Cloud optical depth at 550 nm. f Cloud ice water path. For c–f only pixels with a BTD greater than 15 K are shown. Maps and satellite imagery were generated and processed by the authors with Python 3.9.9 using the Matplotlib 3.5.1 and SatPy 0.33.1 packages.
