Polar Operational Environmental Satellites (POES) Extended Life is a NOAA initiative to extend the value of its POES satellite constellation (NOAA-15, NOAA-18 and NOAA-19), under a best-effort approach - see NOAA announcement.
In this context, the way these satellites are operated will change: they will transition to being operated by a new commercial ground system service. Due to this new approach, contingency data recovery will not be performed and extended data disruptions could occur periodically because of operational constraints.
The operations transition period will span from May until September 2023.
This will affect the way we provide NOAA-19 data to our users. Currently, the GAC (Global Area Coverage) raw data (Level 0) from NOAA-19 are transferred to EUMETSAT Central Facility for processing and distribution to end-users. With the new configuration, this will no longer be possible.
We will, therefore, provide the equivalent NOAA-19 Level 1 sounder data generated by NOAA, through the Global NOAA ATOVS L1 service. NOAA-19 AVHRR and ATOVS-L2 data will be discontinued with this transition.
Note: the Global NOAA ATOVS L1 service currently provided by EUMETSAT consists of NOAA-15 HIRS and AMSU-A data and NOAA-18 HIRS, AMSU-A and MHS data.
We are planning to start distributing NOAA-19 sounder data (AMSU-A, HIRS and MHS) as part of the Global NOAA ATOVS L1 service, from 24 May 2023.
These data (full dump) will be distributed on EUMETCast in parallel to the current NOAA-19 data stream (provided in 3-minute granules) which will remain available until NOAA transitions NOAA-19 to the new operational configuration (currently foreseen in July 2023).

Multicast address: 220.127.116.11
Multicast address:: 18.104.22.168
The new NOAA-19 data stream, part of the Global NOAA ATOVS L1 service, will become the operational data stream from 14 June 2023. At this point, the current NOAA-19 data stream (provided in 3-minute granules) will be provided only on a best effort basis.
On 14 June 2023, the NOAA-19 data stream part of the Global NOAA ATOVS L1 service will also start being distributed on the GTS, replacing the current NOAA-19 data stream on GTS.
The BUFR bulletin headers will be the same as those currently used for the NOAA-19 data:
AMSU-A: INAX11-19 EUMP
HIRS: INHX11-19 EUMP
MHS: INMX11-19 EUMP
Users who are already subscribed to receive Global NOAA ATOVS L1 data via EUMETCast will receive the NOAA-19 data automatically. Other users wishing to receive these data should register via our Earth Observation Portal (EOP).
