OpenSkiron no longer responds !

Posted on

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.

Apparently, probably due to their Israeli connections, David Gal's website was the victim of a serious computer attack. Thus, OpenSkiron is expected to be offline for a while. It remains to be hoped that he will be able to resume his activities as quickly as possible.. (²)

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