We are currently actively working on a fix to overcome problems with temporarily unavailable data in MARS.
If you get the MARS error 'Requested data is on one or more damaged tape: tape_name' please use the form below to check for the relevant tape_name. Below you can also search a list of common ECMWF datasets affected by these tape problems. The search results will give you a good indication on the data currently not accessible, e.g. the line
/mars/prod/tigge/o/g/cf/sfc/marstiprod/glob/cf/sfc/2018/20181023.0600.222067.20181025.053439
shows that the Surface (sfc) Control Forecast (cf) TIGGE global production data for the 06 UTC run on 23 Oct 2018 is currently not available.
If the data you are interested in is listed in any of the search results we are already aware of the issue and working on the data recovery. There is no need to notify us about the problem. Please check here again later. For any other problem with MARS access, please visit the online documentation or feel free to contact us.
We apologise for any inconvenience any temporary unavailability of data may cause you.
