title0716-11-2017 New ISAC fixed reforecast set

New fixed ISAC reforecast set was added to S2S archive. The new model version date it relates to is 2017-06-08. The new reforecasts contain now newly perturbed outputs as well and the lead time has been extended to +32 days. The data availability can be discovered as usually via the dedicated S2S data portal at ECMWF.

HW issue affecting some S2S hindcasts availability

We have recently experienced a couple of hardware incidents with tape volumes becoming damaged:

  1. During October 2017, a large proportion of hindcast (enfh), perturbed forecast (pf), single level data (sfc) was not available from tape. Data cached on disk would not be affected, but
  2. From beginning of November 2017 (still on-going), half of the hindcast (enfh), perturbed forecast (pf), pressure level data (pl) are not available from tape.

Unfortunately, requests for data from damaged tapes will block access to all S2S data. In order to prevent no S2S service, we have disabled access to (2)

We apologise for any inconvenience and will update you when the access to all hindcasts is restored

title03-11-2017 Update on the data issues in Meteo-France outputs

The Meteo-France ssrd field is actually correct. The issue described previously only concerns the French seasonal forecast system but not the S2S one. However there is a newly acknowledged 10-meter wind fields issue - both the zonal and meridian components are effectively wrong. For more details go to the data issues page.

title0107-11-2017 New JMA ISAC fixed reforecast set

New fixed JMA ISAC reforecast set was added to S2S archive. The new model version date it relates to is 2017-0106-31. Comparing to the previous set of JMA reforecasts (with the preivous model version date 2014-03-04)  it has two more year longer reforecast period 1981-201208. The new reforecasts contain now newly perturbed outputs as well and the lead time has been extended to +32 days. The data availability can be discovered as usually via the dedicated S2S data portal at ECMWF.

title19-10-2017 Issues with some pressure level KMA data fixed03-11-2017 Update on the data issues in Meteo-France outputs

The Meteo-France ssrd field is actually correct. The issue described previously only concerns the French seasonal forecast system but not the S2S one. However there is a newly acknowledged 10-meter wind fields issue - both the zonal and meridian components are effectively wrong. For more details go to the data issues pageThe problems with U/V  and geopotential fields (500 hPa and higher levels only) in pressure level outputs from KMA were fixed. The affected data in MARS was re-archived (period between the 29th March and end of August, 2017). For more details, please visit the page about Issues with data.

title09-10-2017 Issue with data (Meteo-France, ssrd)

All surface solar radiation downwards (ssrd) data  from Meteo-France is wrong.  Please see update from 03-11-2017 above. For more details go  to the data issues pageBecause of a HW issue with one of the archiving tape some hindcast data is not available since the end of September. The total volume of the currently unavailable data is 50 TBytes i.e. 20% of all S2S reforecasts is affected. The exact file list could be checked here. The tape has been sent for data recovery.  We apologize for any inconvenience.
