23-03-2016 More issues with data: problems with sea-ice cover from CMA and BoM

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.

08-03-2016 ECMWF forecast system change

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;

06-10-2015 Scripts to help retrieving reforecasts data

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.
