CSPP GeoSphere<\/a> allows a user to view True Color imagery (and individual GOES-16 bands) in real time using data from the four GOES-16 domains:\u00a0 Full Disk, CONUS, and Mesoscale Sectors 1 and 2.\u00a0 The animation above shows the 1330 UTC eruption (11 April 2021) of Soufriere, one of a series of eruptions from that volcano (as discussed here <\/a>and elsewhere).\u00a0 The ash emitted by the short (duration) eruption then moves westward towards Barbados, following upper-level winds.\u00a0 (Low-level winds are easterly).\u00a0 The rapid ascent of the ash cloud is documented below, showing 4 images from the Full Disk imagery at 1320, 1330, 1340 and 1350 UTC.<\/p>\n

Rapid changes suggest Mesoscale imagery would be useful.\u00a0 Indeed, volcanic events area ranked #2 on the GOES-R MDS Priority List<\/a>, after only a SPC<\/a> High\/Moderate Risk for Severe weather.\u00a0 Thus, mesoscale Sector 2 imagery was available over the area.\u00a0 \u00a0That is shown below and it better captures the time of the eruption and better resolves the ascent through the troposphere.<\/p>\n

Seven consecutive zoomed-in 1-minute images are shown below, from 1329 through 1336 UTC on 11 April (with the map removed; CSPPGeo link used here<\/a>; a similar animation from the CIRA Slider is here<\/a>.) They show the initial stages of this particular eruption.\u00a0 A Pileus cap is obvious at the top of the eruption at 1329 UTC. (Animation available here<\/a> as an mp4).<\/p>\n
