The launch and post-launch checkout of GOES-14 allows a comparison of the sounder instruments on GOES-14 (see the image above) and GOES-12, the operational GOES-East (the image below). The Sounder is used to detect emitted radiation at 19 different wavelengths, in contrast to the 5 wavelengths sensed by the Imager.... Read More
Unseasonably cool air over the Midwest combined with warm late-Summer lake surface temperatures to sustain a line of lake-effect showers that came ashore over southern Lake Michigan on Sunday Morning. A very sharp-edged narrow cloud feature extended north-northeastward from southern Lake Michigan towards northwestern lower Michigan. Lake surface temperatures temperatures... Read More
GOES-14, which was launched on 27 June and is now undergoing post-launch check-out, is over the Equator at 90 degrees W longitude, whereas GOES-12, the operational GOES-East, is over the Equator at 75 W Longitude. The two satellites give slightly different views of Hurricane Bill, and stereoscopy can be used to view the visible imagery, allowing... Read More
Super Rapid Scan Operations are called on GOES-East or GOES-West when meteorologists want to investigate phenomena that occur over very short timescales. Typically, SRSO imagery is taken every minute. However, gaps exist because of responsibilities to other regions. For example, when the National Hurricane Center requested SRSO observations of Hurricane... Read More
