Good News!! GOES-13 is back online. Solar Radiation Data is Available For Downloading

Good News!!  GOES-13 is back online.  Solar Radiation Can be downloaded by clicking HERE

The GOES-13 satellite was offline from September 25 through October 19, 2012.  During this time, solar radiation data for PR and the northern Caribbean Region were not available.  However, the water and energy balance algorithm (GOES-PRWEB) continued to function with estimated solar radiation data.  GOES-PRWEB results for solar radiation and 24 other hydro-climate variables are available at


Solar Radiation Data Derived from GOES-13 Down Until Further Notice

Solar radiation data for Northern Caribbean Region (2 km) and Puerto Rico (1 km), derived from GOES-13 will not be available until further notice.

The National Oceanic and Atmospheric Administration (NOAA) confirmed September 26, 2012, that GOES-13 has been placed in stand-by mode, following increased vibrations, or “noise,” observed in the imagery.  For more information visit

As I understand it, the short-term plan is to move GOES-14 further east to pick up most of the area covered by GOES-13.  Evidently the satellite coverage area will move eastward at 0.9 degrees per day until it moves to the new position.  Yesterday’s solar radiation data, estimated from an algorithm run at the University of Alabama, resulted in the following map:

The above data are clearly wrong, but it may be an indication of how the coverage area of GOES-14 has shifted eastward, relative to its original position shown on the day that GOES-13 went down in the following figure.

The long-term plan (around 2015) is to replace the current satellites with GOES-R, which will provide more channels, and higher space and time resolutions.
