OSISAF HL News http://osisaf.met.no News and Service Messages for the EUMETSAT Ocean and Sea Ice SAF High Latitude Center. en OSISAF logo http://osisaf.met.no/logos/OSISAFLogo_solid_S.jpg http://osisaf.met.no Fri, 11 May 2012 13:55:35 +0000 hourly 1 Mon, 14 May 2012 00:00:00 +0000 Mon, 14 May 2012 - Upgraded NetCDF format for Sea Ice products http://osisaf.met.no/news/#96 The NetCDF format of the OSI SAF Sea Ice Concentration, Edge and Type products (OSI-401, OSI-402 and OSI-403) have been upgraded, as well as the file name convention. The reprocessed Sea Ice Concentration product (OSI-409) and LR Sea Ice Drift (OSI-405) product have not been changed. The reason for these changes is to provide all ice products using the same meta data convention (CF-1.4) and to harmonize the content of these three products with the more recent released OSI-405 and OSI-409 products.

More detailed information about the upgrade is available here: http://osisaf.met.no/p/ice/new_ice_netcdf_format.html

To assure that the users have good time to adapt to the new format specifications, the old format will be provided in parallel with the new format until 15th September 2012.

The missing products will be reprocessed and will be available on our FTP server (ftp://osisaf.met.no/prod).

]]> Mon, 23 Apr 2012 00:00:00 +0000 Mon, 23 Apr 2012 - OSI SAF Sea Ice: missing products http://osisaf.met.no/news/#94 Due to an unexpected problem with the delivery of SSMI input data to the OSI SAF, we have not been able to produce any sea ice products since 21. April. The problem has been reported to the data provider, and we are hoping for a quick recovery.

If all goes well, we might be able to deliver ice concentration, edge and type products as nominal tomorrow morning, 24-04-2012.
Sea ice drift products will be two days more delayed, since it uses three days of data.

]]> Fri, 3 Feb 2012 00:00:00 +0000 Fri, 3 Feb 2012 - OSI SAF Sea Ice: partly missing input data http://osisaf.met.no/news/#93 Due to outage of SSMI data from our data provider, yesterdays (produced today) OSI SAF Sea Ice Concentration, Edge and Type products contain some missing data areas.
The data stream is now back to nominal and the next sea ice products should be complete.

]]> Mon, 2 Jan 2012 00:00:00 +0000 Mon, 2 Jan 2012 - Delayed sea ice products http://osisaf.met.no/news/#92 Due to a problem with the distribution of products to our FTP server, the sea ice products were 3 hours delayed at the OSI SAF FTP server today. The distribution is now back to nominal.

]]> Thu, 15 Dec 2011 00:00:00 +0000 Thu, 15 Dec 2011 - Missing low resolution ice drift product http://osisaf.met.no/news/#91 The low resolution sea ice drift production failed this morning. The production has been re-run and the latest product is now available through our FTP server as usual, ftp://osisaf.met.no/prod

]]> Tue, 13 Dec 2011 00:00:00 +0000 Tue, 13 Dec 2011 - SSM/I input data back to nominal http://osisaf.met.no/news/#90 The SSM/I data stream from NOAA is now back to nominal, and data since 09UTC are available. The OSI SAF sea ice products might still experience missing data areas in the the product that will be distributed around 04 UTC tomorrow (14-12-2011).

]]> Tue, 13 Dec 2011 00:00:00 +0000 Tue, 13 Dec 2011 - Missing SSM/I input data http://osisaf.met.no/news/#89 Due to a problem with the data flow of SSM/I data to NOAA, the OSI SAF has not received SSM/I data since yesterday afternoon. This results in missing orbits of input data to the sea ice concentration, edge and type products and there are a few holes of missing data in the products dated 12.12.2011.
This issue has been reported and we hope the problem will be sorted out soon.

]]> Mon, 12 Dec 2011 00:00:00 +0000 Mon, 12 Dec 2011 - Update for Sea Ice Concentration, Edge and Type http://osisaf.met.no/news/#88 The NWP input data for the OSI SAF global sea ice concentration, edge and type products have been updated on 12-12-2011. These products now use the 0.25 degree resolution ECMWF NWP fields for the atmospheric correction that is applied to the brightness temperatures. Previously the 0.5 degree resolution fields were used. The update has a minor positive effect on the sea ice products.

]]> Wed, 7 Dec 2011 00:00:00 +0000 Wed, 7 Dec 2011 - New version of reprocessed sea ice concentration data set http://osisaf.met.no/news/#87 The OSI SAF reprocessed sea ice concentration data set (OSI-409) has been updated and a new version v1.1 released. Two changes has been introduced to the new version of the data set:
  • Fixed bug in uncertainty estimates.
  • Extended data set period, now covering October 1978 - October 2009.
The new version of the data set, updated documentation and quick looks are available at the OSI SAF sea ice web portal:

28.10.2011 - EUMeTrain presents Ocean and Sea week training sessions

From 31 October to 3 November 2011 the EUMETSAT-sponsored training project EUMeTrain will host an event week on Ocean and Sea applications.

This EUMeTrain event week consists of several online sessions. The event week should serve as an exchange on the experience for the forecasting on shiproutes, but also advocate the benfits that the use of ASCAT data (Metop) as well as the radar altimetry data povided by Jason-2 can have to the operational maritime forecaster.

Registration for this event week is required. When you have registered you will automatically receive the required invitation. For those of you that will miss this event, all the sessions will be recorded for download.

EUMeTrain is EUMETSATs largest international training project which develops training material and the supports training in the field of satellite meteorology in combination with other meteorological data sources. EUMeTrains main goal is training and providing training material, supporting the EUMETSAT programs with special weight on hazardous weather events.

Further information on the event and the full timetable are available on the EUMeTrain website.

Note that this did not impact distribution on EUMETCast.
All systems are back to normal now.
