Acknowledgements

The GOES Science Tests occur at the end of long Post Launch Test (PLT) periods for each satellite and arepossible because of the cooperation of NASA and NOAA/OSD and OSO personnel, who in particularprepare 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 thefollowing:

1)To assess the quality of the GOES radiance data. This isaccomplished by comparison to other satellitemeasurements or by calculating the signal-to-noise ratiocompared to specifications, as well as assess the striping inthe imagery due to multiple detectors.

2)To generate products from the GOES data stream andcompare to those produced from other satellites. Theseincluded several Imager and Sounder products currentlyused in operations.

3)Rapid-scan imagery of interesting weather cases arecollected with temporal resolutions as fine as every 30seconds, a capability of rapid-scan imagery from GOES-Rthat is not implemented operationally on current GOES.

The NOAA Science Test does not involve the solar instrumentation.

GOES-14 Science TestDecember 2009

•Five (5) weeks:

–Starting: 30 November 2009

–Ending: 04 January 2010

•Eight (8) pre-determined schedules (Seehttp://rammb.cira.colostate.edu/projects/goes-o/#schedules

•Daily schedule changes (at 1630 UTC), determined bytest coordinators, based on feedback fromparticipating scientists

•GOES-14 will be located at 105°W during the ScienceTest

•Afterwards, GOES-14 will be kept in normal mode andthe solar instruments only will be operational.

GOES-14 Science Test Preliminary Results

• First official GOES-14 images were collected fromImager (visible and IR) and Sounder

• Improved (4 km) resolution of 13.3 µm band requiredchanges to GVAR format.

• Several issues with implementing the new GVAR formatwere discovered and are being rectified, both at the frontend, and at GVAR receiving sites.

• Paired detectors on the higher-resolution 13.3 µmband were inadvertently swapped. Now fixed.

• Image navigation issues have been addressed(McIDAS server software was upgraded.)
