2016

Sea-ice cover data from BoM and CMA have problems, mostly in the re-forecast. Users are recommended not to make use of this data until it has been replaced in the S2S Archive, which we aim to do in the coming weeks. This will be announced to users. For more details, please visit the page about Issues with data.

Update of ECMWF forecast system. A new version of ECMWF model (IFS cycle 41r2) was introduced at ECMWF. 

The main consequences for ECMWF-S2S data are:
  • Introduction of a new model grid: the reduced Gaussian octahedral grid;
  • Horizontal resolution of the ENS increased from TL639 / N320 to TCO639 / O640 for ENS (Days 0 - 15) and from TL319 / N160 to TCO319 / O320  for ENS Extended (Days 16 - 46), where subscript C stands for cubic and O for octahedral;
  • For the medium-range ENS there will no longer be a decrease of resolution at day 10: the ENS Days 11 - 15 will be run at the same TCO639 / O640 resolution as ENS Days 0 - 10;

The new upcoming version of ECMF model has been tested. Both runs Monday's and Thursday's of real-time forecast and hindcasts have been tested to be prepared for smooth switching to the new version soon.
The on-the-fly produced UKMO reforecasts have been added to S2S database with the 1st archived date January 1, 2016. More information ... here.
NCEP reforecasts archiving for the fixed period 1999-2010 was completed. The whole period is now fully available for users.

2015

The real-time part of UKMO model outputs started to be archived in S2S database since December 1, 2015. More information ... here.
The model outputs from ISAC-CNR were added to S2S database. The 1st available date is November 9, 2015. More information ... here.

A page Issues with data was created with the intention to make users aware of important issues with the data. We suggest users to 'Watch' that page so they should get notified of any issue we believe is relevant. More information... here.

We have documented a couple of cases on how to write scripts to retrieve data efficiently via the WebAPI. In order to do that one needs to know the frequency and availability of each Centre's reforecast. These use cases are linked in the page with models' description (click on the model name in the first column there)

For example the links to BoM or CMA use cases are here:
BoM: https://software.ecmwf.int/wiki/display/S2S/BoM+reforecast+efficient+retrieval
CMA: https://software.ecmwf.int/wiki/display/S2S/CMA+re-forecast+efficient+retrieval

The web interface to access reforecasts was opened. The interface is available here.

The reforecast frequency was changed from once to twice per month. More information... here.

The real-time part of HMCR model was added to S2S database. More information ... here.
A new model was added to S2S database. More information ... here.
A new model was added to S2S database. More information ... here.

The major difference for S2S database is the model running frequency change to twice a week and the extension of the forecast length to 46 days. More information ... here

The official launch of S2S database 

Near real-time forecasts from four data providers (BoM, ECMWF, JMA and NCEP) have been ingested routinely since January 2015.
