GOES-16 (GOES-East) Split Window Difference (10.3-12.3 µm) along with SO2 RGB and Ash RGB images (above) displayed signatures of volcanic clouds produced by a sequence of eruptions of Popocatépetl in Mexico on 21 February 2024. Although these volcanic clouds apppeared to be predominantly ash-dominated (shades of pink to magenta in the Ash RGB,... Read More

A distinct hot thermal signature (black to yellow to red pixels) of a new Sundhnúkagígar fissure eruption on the Reykjanes Peninsula in southwestern Iceland was apparent in GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) imagery on 08 February 2024 (above). Station identifier BIRK is Reykjavik Airport, and BIKF is Keflavik International Airport.Since the... Read More

5-minute CONUS Sector GOES-16 (GOES-East) Ash RGB, Dust RGB, SO2 RGB and Split Window Difference images (above) displayed signatures of a series of volcanic cloud pulses produced by minor eruptions of Popocatépetl on 27 January 2024. This comparison highlights the fact that the Ash RGB might not always provide the best depiction of volcanic cloud structure... Read More
