8. South America RSO Frames Created 8 South America Central (SAC) South America South (SAS ) GOES-13 (East) Rapid Scan Operations (RSO) South America Frames were created to drastically improve coverage

9. GOES-West Alternate RSO Restored As a result of recent testing, at NESDIS, the NWS and CIMSS, GOES-15 (West) is once again able to call Rapid Scan Operations (RSO) over Hawaii RSO was then called for almost 6 days to monitor Tropical Cyclone Ana http://cimss.ssec.wisc.edu/goes/blog/archives/16856 http://cimss.ssec.wisc.edu/goes/blog/archives/17027 9 Alaska FramesHawaii TPARC SITKA American Samoa

10. A correction that re-claims previously missing Sounder data was developed by OSPO, working with Exelis and others. These re-claimed data were provided, and then qualitatively and quantitatively analyzed at CIMSS. This correction is now operational (March 2014). GOES-13 Sounder water vapor band (11) showing the missing data with the current image (left), along with the corrected and re-processed image (right) with a test version of the SPS (Sensor Processing System). While one band is shown, all GOES-13 Sounder bands are affected. GOES-13 Sounder Dropped Data 10

11. Working with NOAA NESDIS OSPO for testing an updated GOES Imager co-registration correction.

12. GOES-14 Super Rapid Scan Operations (SRSOR) GOES-14 provided very unique data and offered a glimpse into the possibilities that will be provided by the ABI on GOES-R in one minute mesoscale imagery Past GOES-14 SRSOR schedule Jun 12–14, Aug 19–28, 2013 May 8–22, Aug 14–28, 2014 http://cimss.ssec.wisc.edu/goes/srsor2015/GOES- 14_SRSOR.html http://cimss.ssec.wisc.edu/goes/srsor/GOES- 14_SRSOR.html http://cimss.ssec.wisc.edu/goes/srsor2013/GOES- 14_SRSOR.html http://cimss.ssec.wisc.edu/goes/srsor2014/GOES- 14_SRSOR.html SRSOR plans for 2015 include May 18-Jun 12, and Aug 10-22 http://cimss.ssec.wisc.edu/goes/srsor2015/GOES- 14_SRSOR.html 12 GOES-14 visible image showing rapid convective development

16. Backup

17. GOES Product Impacts GOES-13 SXI detector damaged due to 2006 flare. 9 rows currently affected out of 512 total. GOES-14 products are all nominal. GOES-15 Sounder temperature control blanket is raised. -Requires a yaw flip at Equinox to keep Sun angle below cooler plane. -1 hour data outage and degraded products during 26 hours of INR recovery. GOES-13 XRS X-ray measurements can potentially invert unexpectedly. 17

18. GOES-12 Decommissioned Launch: Jul 23, 2001 GOES East at 75 o W: Apr 1, 2003 – Apr 14, 2010 GOES South America at 60 o W: May 10, 2010 – Aug 15, 2013 Decommissioned: Aug 16, 2013 Extensive end-of-life Sounder filter wheel testing was conducted toggling filter wheel windings and electronics Single string thrusters were used to boost GOES-12 350 km above GEO orbit GOES-12 captured this visible image of Hurricane Katrina shortly after landfall on August 29, 2005. 18 Sample coverage from GOES-12 imager when at 60 degrees West

19. GOES-15 Star Tracker 1 Failure GOES-15 Star Tracker 1 (ST1) failed - caused GOES West schedule to be disabled on Jul 15, 2014 GOES West scan operations resumed 6 hours later and the S/C was running with single star tracker (ST3) Short Span Attitude Adjusts (SSAA) were enabled to maintain Image Navigation and Registration (INR) operations ST2 was powered on and configured for ST2-ST3 on Jul 17 S/C is performing nominally as GOES West 19

20. Improved Eclipse Operations GOES-15 experienced a 37 km grid shift on Sep 9, 2013. Degraded star measurements caused by corrupted stars produced a bad eclipse IMC set. During eclipse, star measurements degrade due to thermal shifts in the secondary telescoping mirror and “potato chipping” of the scanning mirror. The OATS software was modified to account for the double peak stars during eclipse. This software correction will protect against a similar situation in the future. Uneven Heating of the Secondary Telescoping Mirror during Eclipse Double Peak Star 20

21. GOES Data in NWS NWP Models 21 Instrument & ProductsGFSNAMHRR R Sounder Radiances (clear sky) Yes Atmospheric Motion Vectors - Infrared and water vapor Yes Imager and Sounder Products - Cloud Products Yes Sea Surface TemperatureYes GOES Fires (WFABBA)Yes GOES Cloud-top coolingYes GOES data are key in NWP, both global and regional models. GOES products have also been used to tune/validate models, for example, GOES cloud products go into RTMA which is used to verify NAM and GFS. The GFS is used for boundary conditions for regional models.

22. GOES-13 Momentum Anomaly S/C lost attitude knowledge and was transitioned to safe hold on May 22, 2013 Anomaly was caused by physical momentum exchange Torque plane analysis suggests the most probable cause is micrometeoroid/space debris hit on the lower yoke S/C recovered to normal mode operations on May 29 and all units are operating nominally S/C Sounder outgas performed from May 31 - June 4 S/C is performing nominally as GOES East since June 10, 2013 GOES-14 was brought out of storage and served as GOES East from May 23 – June 10 22 Impact Area (Net Force)
