Updated December 1, 2018

GOES-15
GOES-15 completed  drifting east to its new operational location of 128º West on November 7, 2018 . SDS will continue to make GOES-15 data available via the ADDE datasets WESTS and WESTL.

GOES-17
GOES-17 completed drifting west to its operational location of 137.2º West on November 13th, 2018.  As of November 15th, 2018 at 15:00 UTC, new data is available via the SDS ADDE datasets WESTA, WESTAL, WESTB, WESTBL.

Per an update on Dec 1, GOES-17 will remain non-operational through December in order to finish additional testing. After testing concludes, the satellite will go into operations as the GOES-West satellite.   NOAA is aiming to complete this process in January 2019.

User Action is Required
We highly recommend users start preparing for this change as soon as possible.  ABI instruments exhibit many differences in channels, coverages, data volume, and resolution in comparison to current GOES-West (GOES-15). See details at the bottom of this page.

There will be a 6-month overlap of GOES-17 transmission with GOES-West (GOES-15).

Differences between GOES-17 ABI and GOES Imager

  • GOES ABI transmits 16 channels compared to current GOES’s 5.  ABI channel and resolution do not match those of current GOES
  • When requesting images by time,  the seconds must be included E.g. TIME=12:15:37
  • Scanning differences – GOES-17 is expected to primarily transmit data in MODE 3.
    • MODE 3 sends:
      • FD (Full disk) images every 15 minutes at approximately XX:00:37, XX:15:37, XX:30:37, and XX:45:37
      • M1 or M2 (Meso scale sector 1 or 2) every minute offset by 30 second
        • M1 is at XX:XX:26
        • M2 are then at XX:XX:56
        • If M1 and M2 are scanning the same mesoscale sector, there will only be an M1 coverage, but at XX:XX:26 and XX:XX:56

XX:02:18
XX:07:18
XX:12:18
XX:17:18
XX:22:18
XX:27:18
XX:32:18
XX:37:18
XX:42:18
XX:47:18
XX:52:18
XX:57:18

    • MODE 4 sends:
      • FD (Full disk) images every 5 minutes.  No meso sectors
      • CONUS (Continental US coverage) These ARE subsetted from FD.
      • No meso sectors
  • There are 6 ABI ADDE datasets
    • ALL  – All coverages
    • FD – Full Disk coverage
    • CONUS – Continental US coverage (these images are not a subset of the FD in MODE3, but they are a subset of FD in MODE4)
    • M1 – Mesoscale sector 1
    • M2 – Mesoscale sector 2
    • M – Both  Mesoscale sector 1 and Mesoscale sector 2
  • There are 3 GLM ADDE datasets
      • GLM-EVENT  – GLM Event Data
      • GLM-FLASH – GLM Flash Data
    • GLM-GROUP – GLM Group Data
  • There is no sounder on GOES-17 (GOES-R series) satellites
  • ADDE servers cannot “follow/track” images at this time
  • Data may come from 1 of 2 sources PDA via STAR or Direct Broadcast.  In most cases data will be from Direct Broadcast. The switch between users should be transparent, although data from the PDA via STAR may be delayed by 20 minutes or more.
  • There is a RabbitMQ event service available to alert users of new data availability for every image.   If you are interested in information on or subscribing to this service, please contact SDS sds@ssec.wisc.edu .

 

Satellite Transition Timeline

  • October 17, 2018 at 15:00 UTC, GOES-15 GVAR will begin relay through GOES-14 (transparent to SDS users)
  • October 29, 2018 at 20:15 UTC GOES-15 begins drifting east from 135º West
  • October 24, 2018 at 17:40 UTC GOES-17 begins drifting west from 89.5º .  During the drift only MAG will continue to operate but with nominal data distribution. All other instruments will be put in either safe or diagnostic modes or disabled.
  • November 7, 2018 at 19:00 UTC, GOES-15 reaches its new operation location of 128º West
  • November 13th, 2018, GOES-17 reaches its operational location of 137.2º West
  • January 2019 date tbd, GOES-17 becomes the operational West satellite
