The second volcanic plume moving northwestward — which exhibited subtle signatures in the Split Window and RGB images — extended to an altitude of 24,000 feet. Although neither the Split Window nor the RGB images showed strong volcanic cloud signatures, taken together they helped to confirm the presence and transport of the 2 separate plumes.<\/p>\n GOES-16 Split Window (10.3 – 12.3 \u00b5m)<\/em> image showing the text of the 1323 UTC Volcanic Ash Advisory [click to enlarge]<\/p><\/div>The radiometrically-retrieved Volcanic Ash Height product from the NOAA\/CIMSS Volcanic Cloud Monitoring<\/strong><\/a> site indicated a maximum height in the 5-7 km range for the westward-moving plume (below)<\/strong><\/em>.<\/p>\n<\/a>
