OpenSkiron no longer responds !

Posted onLeave a comment

For just over a month the website OpenSkiron which delivers the GRIB files for free OpenWRF is no longer available. These alternative high-resolution files (¹) provide fine grid coverage of the Mediterranean, where the Arome model stops.

David Gal is a scientist attached to The Leon Recanati Institute for Maritime Studies in Haifa.
