Each year, about every 6 months, the Earth-Sun-Satellite geometry is such that the GOES Imager can look right at the Sun. In the past, there were ‘keep-out zones’ in which the satellites did not image because it was known to be looking at the Sun during those times. The imagery... Read More

GOES-14 came out of storage in mid-August for an annual north-south maneuver and for GOES-R Testing.

It will... Read More

GOES-13 replaced GOES-14 as the operational GOES-East satellite at 1444 UTC on 18 October 2012. The image above shows the 5 imager channels at 1445 UTC.In September of 2012, Imagery from both the GOES-13 Sounder and from the GOES-13 Imager showed increasing amounts of noise. On September 23, 2012, GOES-13 was... Read More

The GOES Imager infrared channels are displaying increasing amounts of small-scale noise that is manifest in imagery as herringbone or checkerboard features, as shown in the comparison above with a MODIS water vapor imagery. The animation below, an AWIPS composite of GOES-13 and GOES-15, shows increasing amounts of noise with... Read More
