All LRIT West Users:

There is now a MTSAT, LRIT, Infrared Channel, Full Disk Image being re-formated into a NOAA GOES LRIT Image every hour and broadcast over GOES West.



Previous Notices

All LRIT Users:

The following is the most current GOES-11 to GOES-15 Transition Schedule.
Note that EMWIN from GOES-15 became available on November 28th.
Note that LRIT will be a "hot" turnover on December 14th at 16:20 UTC.


GOES-11/GOES-15 upcoming schedule:
11/28 - Turn on GOES-15 EMWIN
12/06 - GOES-15 GVAR patch through GOES-11 @ 1550z (GOES-15 becomes GOES-West)
        Stop GOES-11 schedule, Start GOES-15 imaging data
        User continues to receive GVAR through GOES-11
12/07 - Backup date for 12/06 in case of critical weather day
12/13 - GOES-15 drift stop maneuver @ around 0200z (no backup date)
12/14 - GOES-15 GVAR through GOES-15 @ 1552z
        User starts to receive GVAR through GOES-15
12/14 - Turn off GOES-11 DCS/SAR/LRIT/EMWIN and turn on GOES-15
        DCS/SAR/LRIT @ 1620z
12/15 - Backup date for 12/14 in case of critical weather day
12/16 - GOES-11 deorbit maneuver #1 @ 0230z
12/16 - GOES-11 Deorbit maneuver #2 and final decommission @ 1430z


LRIT and EMWIN will transition to HRIT/EMWIN on the GOES-R Series of Satellites:

On the next series of Geostationary Operational Environmental Satellites, GOES-R, both the Low Rate Information Transmission (LRIT) and the Emergency Managers Weather Information Network (EMWIN) will be combined into a single broadcast. The new service will be called HRIT/EMWIN (HRIT stands for High Rate Information Transmission). The GOES-R program "With the encouragement from NWS (operator of the EMWIN Program) and NESDIS (operator of the current GOES LRIT service) the GOES-R program undertook a technology demonstration program to show that relatively inexpensive receivers designed for the new service could: Support not only HRIT/EMWIN but all of the predecessor services, eliminating costly and disruptive changes to the user systems as the services evolve from the GOES-I-M era, to the GOES-NOP Series, and finally to the GOES-R Series." More information about the HRIT/EMWIN service and the HRIT/EMWIN prototype receiver can be found at http://www.goes-r.gov/users/hrit.html.
