title13-05-2021 S2S documentation improvement

S2S documentation pages have been redesigned and updated to help users better understanding of model configurations and their changes since the project start. The main table in Models has now a feature Expand/collapse the table allowing quick overview of each model major changes impacting products for S2S. Also separate pages dedicated to each model have been updated so that users could identify model change to its previous version more easily. Complete overview of all model configurations since S2S project start should hopefully help users also to define their data retrievals for extended period of time and in more efficient way too.

title06-02-2018 HW issue affecting some S2S hindcasts availability

We have recently experienced a hardware incident with a tape volume becoming damaged:

  • From 31 December 2017, half of the hindcast (enfh), perturbed forecast (pf), pressure level data (pl) are not available from tape. Note data cached on disk is still available.

Unfortunately, requests for data from a damaged tape are blocking access to all S2S data. In order to prevent blocking all S2S service via the WebAPI, we have disabled access to that specific dataset (reforecast, perturbed forecast, pressure level) until the problem is resolved.. We apologise for any inconvenience.

As of 19:00 UTC access to all hindcasts has been restored.
