This report covers the 7-months’ period June–December (H2) of 2023. During this period the following ROM SAF data products have been produced and disseminated: Metop NRT profiles (since February 2010), Metop Offline profiles and gridded products (since April 2019), Interim Climate Data Records from Metop (since April 2019), Sentinel-6 Non Time Critical (NTC) profiles and gridded products (since December 2021). Since 27 October 2022 demonstration product from commercial RO data (Spire) (purchased by EUMETSAT) has been generated and provided over GTS to NRT users. Commercial NRT data procured by NOAA has been generated as demonstration products as well and disseminated over EUMETCast.

This report covers the 1st half year (H1) of 2013. The ROM SAF level 2 NRT refractivity product (GRM-01) has been disseminated via GTS and EUMETCast with operational status since 1st of February 2010 after being disseminated with pre-operational status since March 2009. A trial dissemination of demonstational Metop-B products on the GTS network (GRM- 40) was started the 10th December 2012, and was stopped the 14th February 2013 due to experimental tests involving new parameter uploads to the Metop-B GRAS receiver firmware. The dissemination of demonstrational Metop-B ROM SAF products was resumed the 4th of April 2013. The Metop-B GRAS instrument parameters where uploaded to the Metop-A GRAS instrument the 25th June 2013. The changed instrument parameters have an impact on the ROM SAF product properties, and a larger number of occultations is now flagged as non-nominal by the ROM SAF quality control. The ROM SAF website has been operational since 2009 and is currently providing access to the ROM SAF help desk, for downloading the ROPP package and for monitoring of product quality. The ROM SAF level 3 climate products based on COSMIC RO data was released the 10th of June 2013. The products are available on the ROM SAF website together with the ROM SAF level 3 climate monitoring plots. The ROPP package ROPP version 6.1 was released the 9th of April 2013. With every new ROPP release the previous version of the ROPP software is continued to be made available though the ROM SAF web site. The last operations review (OR5) was held on the 5-6th of March 2013 at DMI.

This report covers the 2nd half year (H2) of 2012. The ROM SAF level 2 NRT refractivity prod- uct (GRM-01) has been disseminated via GTS and EUMETCast with operational status since 1st of February 2010 after being disseminated with pre-operational status since March 2009.

The ROM SAF website has been operational since 2009 and is currently providing access to the ROM SAF help desk, for downloading the ROPP package and for monitoring of product quality. The ROM SAF website was updated in March 2012. The upgrade was mostly con- cerned with internal data flows and upgrading server operating systems. The new setup will make it easier to maintain and add new features to the website. The ROPP package ROPP version 6.0 was released the 27th of February 2012. With every new ROPP release the previous version of the ROPP software is continued to be made available though the ROM SAF web site. The last operations review (OR4) was held on the 6th of March 2012 at DMI.

The ROM SAF was previously known as the GRAS SAF. The name was changed the 1st of March 2012 when entering the CDOP-2 phase. This report covers the 1st half year (H1) of 2012.

This report covers the 2nd half year (H2) of 2011. The GRAS SAF level 2 NRT refractivity product (GRM-01) has been disseminated via GTS and EUMETCast with operational status since 1st of February 2010 after being disseminated with pre-operational status since March 2009. Due to a bug in the extraction of ECMWF profiles the access to the GRAS SAF background profiles where closed in spring 2011. The bug did not influence the data quality of GRM-01. The bug was corrected, and the corrected code was implemented into the operational system in mid May 2011. The GRAS SAF website has been operational since 2009 and is currently providing access to the GRAS SAF help desk, for downloading the ROPP package and for monitoring of product quality. We are currently in the process of updating the website. The purpose of the update is to make the website more robust and easier to update and maintain in the future. Concerning the ROPP package ROPP version 5.0 was released the 11th of July 2011. With every new ROPP release the previous version of the ROPP software is made available though the GRAS SAF web site. The next ROPP release is planned for February 2012. The last operations review (OR3) was held the 24th of February 2011 at DMI. The next operational review will be held on the 5th and 6th March 2012.
