Dear ROM SAF GTS user



We are pleased to announce the start of the dissemination of

the Metop-B refractivity product (GRM-40) planned to begin on

Monday December 10, 2012, at 12:00 UTC.



The dissemination has the formal status of "demonstration". This is

a best efforts service provided as part of the commissioning activities

related to Metop-B. After the commissioning phase (about February/March

2013) the product will be disseminated with full operational status.



The data are formatted as a BUFR file and disseminated over

the GTS system in near real time. The codes for the GRM-40 BUFR

file is similar to the codes for the GRM-01 BUFR file (Metop-A refractivity),

i.e., the code is "IUT[A-L]14 EKMI" for both Metop-A and -B.

The satellite code (3=Metop-B, 4=Metop-A) is in the BUFR headers.



The refractivity data are generated from the level 1b bending angles

disseminated by the EUMETSAT Central Application Facility since

15 November. The BUFR file also includes a copy of the thinned

version of these bending angles.



In the second half of January 2013 EUMETSAT will be carrying out

a series of parameter upload tests and during this test period

the dissemination will be stopped. When we get closer to this test

period we will be providing more information.



Early January we plan to add the Metop-B data to our NRT monitoring

pages: http://www.romsaf.org/monitoring/

Monitoring of bending angles (including Metop-B) is also available at

the ECMWF monitoring page:

If there are questions please do not hesitate to contact us.



With kind regards

The ROM SAF team
