Currently the mission has two satellites in orbit: Sentinel-2A from 23rd June 2015, and Sentinel-2B from 7th March 2017. Revisit time for this twin constellation is five days. The twin satellites represent a very stable data source, but for the first six operational months (i.e. the second half of the 2015). From the very start of the mission, the Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU) is collecting its own archive of Sentinel-2 data for the extent of the Republic of Slovenia. The data is saved in its original processing state (Level-1C) and in four levels of processing. The archive has now been operating for six full years, which is a good milestone for a statistical overview. We analyse the archive of Sentinel-2 data of Slovenia from several aspects at the country level. A special focus is placed on cloud cover, as only cloud-free data can give an impression of the actual spatial and temporal usability of optical data"},{"@xml:lang":"sl","#text":"Sentinel-2 je visokoločljivostni optični satelitski sistem, ki ga je za Evropsko komisijo razvila Evropska vesoljska agencija (ESA).

Podatke shranjujemo v originalni obliki (tako imenovani produkti L1C) ter v štirih stopnjah nadaljnje obdelave. Arhiv zdaj deluje šest polnih let, kar je zadostno obdobje za statistični pregled. Arhiv podatkov Sentinel-2 smo proučili z različnih vidikov in na ravni vse države. Največ pozornosti smo namenili deležu oblačnosti.
