"IASI Metop-B SO2 Anomaly (148 in [0.0, 3.7]) at (9N,113E) 14:19Z" "2024-04-20 14:19Z granule 287" "See https://www.ospo.noaa.gov/pub/Atmosphere/Soundings/iasi/m01/alerts/Ash_SO2_Anomaly/index.html. Ash BTD is the brightness temperature difference for channel 2347 (1231.5 cm-1) minus channel 2093 (1168 cm-1). SO2 BTD is the brightness temperature difference for channel 3153 (1433 cm-1) minus that of channel 2867 (1361.5 cm-1). Anomaly values equal the ordinary BTD values minus a threshold set to exceed all or almost all recent observations in the local geographic area during periods of low volcanic activity. High ash BTD values may be triggered by dust storms." Latitude (N), Longitude (E), "Ash Brightness Temperature Difference", "SO2 Brightness Temperature Difference", "Ash Brightness Temp. Diff.
