The GOES Science Tests occur at the end of long Post Launch Test (PLT) periods for each satellite and are possible because of the cooperation of NASA and NOAA/OSD and OSO personnel, who in particular prepare the satellite schedules and enable the daily changes that are requested by the science team. Thanks as well to all who contribute to the analysis of the data collected during the Science Tests.
GOES Science Test Goals
For all GOES check-outs, the goals of the Science Test include the following:
To assess the quality of the GOES radiance data. This is accomplished by comparison to other satellite measurements or by calculating the signal-to-noise ratio compared to specifications, as well as assess the striping in the imagery due to multiple detectors.
To generate products from the GOES data stream and compare to those produced from other satellites. These included several Imager and Sounder products currently used in operations.
Rapid-scan imagery of interesting weather cases are collected with temporal resolutions as fine as every 30 seconds, a capability of rapid-scan imagery from GOES-R that is not implemented operationally on current GOES.

GOES-14 Science Test December 2009
Five (5) weeks:
- Starting: 30 November 2009
- Ending: 04 January 2010
Eight (8) pre-determined schedules (See http://rammb.cira.colostate.edu/projects/goes-o/#schedules
Daily schedule changes (at 1630 UTC), determined by test coordinators, based on feedback from participating scientists
GOES-14 will be located at 105°W during the Science Test
Afterwards, GOES-14 will be kept in normal mode and the solar instruments only will be operational.
GOES-O Test Schedules
Limb Sounding (for noise/striping)
CONUS Imager (product generation)
CONUS Sounding (product generation)
Imager rapid-scan (lightning/radar)
Overlapping (ABI 2 km emulation)
GOES-14 Science Test Preliminary Results
First official GOES-14 images were collected from Imager (visible and IR) and Sounder
Improved (4 km) resolution of 13.3 µm band required changes to GVAR format.
Several issues with implementing the new GVAR format were discovered and are being rectified, both at the front end, and at GVAR receiving sites.
- Paired detectors on the higher-resolution 13.3 µm band were inadvertently swapped. Now fixed.
- Image navigation issues have been addressed (McIDAS server software was upgraded.)
