11 11  The data acquired by the satellites are downlinked to the collaborative ground segment from where via ESA network it is being distributed to other sources like Scientific Hub and ESA Server ZAMG (Zentralanstalt für Meteorologie und Geodynamik). From ZAMG, data is pushed to the national mirror and then to the EODC storage. Sentinel-1 data at the EODC warehouse are currently available at approximately 2.5 hours after the initial signal processing by ESA (level-1 product) and 6.25 hours after the acquisition, mostly depends on the timeliness categories. Sentinel-1 level-1 data are archived on fast disks storage and backed up using a robotic tape library on a regular basis.
