Search all nodes for daily ERAINT (evaluation data) at 0.1 resolution. This corresponds to EUR 11 (native uneven grid) or EUR 11i (re gridded fixed grid) in the filename.

Found data on http://esgf-data.dkrz.de/ data node. Could not find the fixed resolution data 11i for daily ERAINT but it should be OK to used native grid which is unevenly spaced.

Here is a link to the filename description http://cordex.dmi.dk/joomla/images/CORDEX/cordex_archive_specifications.pdf

Search on http://esgf-data.dkrz.de/ for

Download the wget shell script and put on /bluepeta/ggsrs/JULES_Forcing/cordex/EUR-11. chmod u+x wget*.sh and run. This will download the data
