The European Union's Sentinel satellites, developed and operated by ESA, will play a critical role in Australia's efforts to manage its vast land and marine environment.

Referring to the news of 29 November announcing the new Sentinel-2 Level-1C products format, ESA is pleased to confirm that the distribution of the new format is effective on all new products since sensing orbit 7608 included, acquired on 06 December 2016.

Please be informed that due to ground segment maintenance activities at EUMETSAT from 6 to 8 December 2016, daily from 07:30 to 17:30 UTC, there will be a risk of data dissemination interruption for all Sentinel-3A products.
A Sentinel-1A satellite unavailability occurred on 04 December 2016 from 06:52 UTC to 11:07 UTC. No SAR data were acquired during this period.

As part of the planned OLCI solar diffuser characterisation campaign, a Sentinel-3A yaw manoeuvre, impacting all instruments pointing attitude is foreseen on 7 December. Reduced data quality should be expected for all Sentinel-3 data products sensed during the below reported periods.

Researchers from the University of Oslo processed and analysed data from the Copernicus Sentinel-1 satellite, which spotted an unusual number of recent avalanches in Svalbard.
