-------- Original Message -------- Topic: GOES-12 to GOES-13 Transition Plan Update Message Issued: April 23, 2010, 1300 UTC Satellites Impacted: GOES-12 and GOES-13 Products Impacted: GOES-12 and GOES-13 Imager and Sounder Data and Associated Products including AWIPS, Ancillary services including DCS, LRIT, EMWIN, and SARSAT. Date/Time of Initial Impact: Pre-operational period begins 1/27/10, Operations begin 4/14/10 1834 UTC ----------------------------------------- Details: Update on GOES-13 schedule: From 4/14 to 4/23, the housekeeping period for GOES-13 was set to 1934 UTC. This is causing the 1930 UTC CONUS image to be missed. On 4/23, the housekeeping period for GOES-13 will be moved to 1534 UTC and remain there. On 4/26/10, GOES-13 will undergo a stop maneuver at 1520 UTC. Following the maneuver, the GVAR and LRIT downlinks will be switched from GOES-12 to GOES-13. * There will be no GOES-13 imaging or soundings from 1515 UTC to 1530 UTC. * GOES-11 will be placed into Full Disk mode from 1515 UTC to 1544 UTC to cover the outage of GOES-13. * At 1520 UTC, GVAR from GOES-12 will be terminated. * At 1530 UTC, GOES-13 LRIT/WEFAX, EMWIN, and PDR will be switched on. * At 1545 UTC, GOES-13 GVAR will be switched on. GOES-13 will resume operations at 1545 UTC following the housekeeping period. Up to date synopsis: (4) On 4/26/10, GVAR and LRIT downlinks will be switched from GOES-12 to GOES-13 when GOES-13 is at 75.5W. GOES-13 will stop drift. Ancillary services (DCS, EMWIN, SARSAT) will switch to GOES-13 at this time. Additional information about DCS transition can be found at: http://www.ssd.noaa.gov/PS/SATS/GOES/THIRTEEN/GOES-13_DCS_Notification.pdf (5) On 4/27/10 at 1848 UTC, GOES-12 will begin eastward drift to 60W in order to replace GOES-10, which was de-orbited in December 2009. Imaging operations for GOES-South America will begin on or about 5/11/10. GOES-12 is expected to arrive on station at 60W on 5/17/10. Users of GOES data and products from ESPC: Following the swap from GOES-12 to GOES-13 on 4/14, several operational products will not be at their optimal accuracy. Since these products require a satellite on station (not drifting) and at least 28 days of data to achieve optimum accuracy, users are advised to take this into consideration when using or viewing these products. They include:- GOES Aerosol and Smoke Product (GASP): Will resume on 5/4/10 with optimum accuracy by the end of May. - Automated Biomass Burning Algorithm (ABBA)
