The GOES-13 Sounder imagery has shown signatures intermittently over the past 4 days that suggest a Filter Wheel Anomaly is ongoing. The image above is from 0246 UTC on 17 July 2012. Similar events occurred on 16 July (at 0046 and 1446 UTC), on 15 July (at 2346 UTC), on 14 July... Read More

On June 20, 2012, the GOES-13 Sounder Filter Wheel mechanism suffered an anomaly. The filter wheel moves the spectral filters into the optical path of sensed radiation. As a result of the anomaly, data quality was degraded starting at about 1248 UTC. Instrument recovery activities occurred at 1756 UTC on 20... Read More

The image above from the SSEC Web Map Service (WMS) shows visible imagery of Tropical Storm Chris over the central Atlantic on June 20th, just south of the north wall of the Gulf Stream. Sea-surface temperatures are indicated by the color shading. The projected path of the storm, and the cone of uncertainty... Read More
