The Sentinel-1B satellite is still finalising its commissioning phase, planned to be completed by mid September 2016. However it was already regularly acquiring data over Central Italy when the 6.2 magnitude earthquake occurred on 24 August 2016.
The Sentinel-1B Single Look Complex products for the passes just before (20 and 21 August 2016) and after (27 and 28 August 2016) the earthquake are available for download on the Sentinels Scientific Data Hub.
These products are not yet fully operationally qualified and are made available as sample products to Copernicus users in preparation for the operational opening of the S1B products after the satellite commissioning is completed. They allow in particular the 6-day S1A/S1B combined interferometric processing over the earthquake area. The corresponding Sentinel-1A products are nominally available as part of the routine Sentinel-1A operations.
