From 19 April 2019, Copernicus Sentinel-3A SRAL L1 SR_1_SRA_A_ and SR_1_SRA_BS reprocessed data will be available through the Open Data Hub and Copernicus Services Data Hub. These products belong to the same reprocessing campaign of SR_1_SRA and SR_2_LAN, which was published in November 2018.

Copernicus Sentinel-1A and -1B are currently unavailable since 18 April at 00:45 UTC and 17 April at 23:55 UTC, respectively, following an issue in the execution of orbit control manoeuvres.

The Copernicus Sentinel-2B acquisition on 12 April with sensing time between 00:55:08 and 00:56:06 - relevant to orbit 10953 - has been lost due to a collision avoidance manoeuvre executed between 11 April at 23:21:36 and 12 April at 01:20:34 UTC.

The complete drying-up of Lake Aculeo in Chile was captured by the Copernicus Sentinel-2 satellite, enabling scientists to follow the water surface extent at high frequency, and thus witness this dramatic loss.

Due to decontamination activities of the Sea and Land Surface Temperature Radiometer (SLSTR) instrument on Copernicus Sentinel-3B, SLSTR products will be degraded and/or missing within the sensing time window of 11 to 17 April 2019.

Records show that, on average, global sea level rose by 3.2 mm a year between 1993 and 2018, but hidden within this average is the fact that the rate of rise has been accelerating over the last few years. Taking measurements of the height of the sea surface is essential to monitoring this worrying trend – and the Copernicus Sentinel-6 mission is on the way to being ready to do just this.

A corrective maintenance to fix a problem on the Copernicus Open Access Hub, caused a service interruption on 11 April from 09:59 to 11:35 UTC.

When we think of climate change, one of the first things to come to mind is melting polar ice. However, ice loss isn't just restricted to the polar regions. According to research published today, glaciers around the world have lost well over 9000 gigatonnes (nine trillion tonnes) of ice since 1961, raising sea level by 27 mm.

Due to an issue at Ground Segment level on 5 April 2019, following Near Real Time/Short Time Critical and Non Time critical Copernicus Sentinel-3A data have been missed:

  • SLSTR  from 20190405T12:04:47 UTC to 20190405T12:38:14 UTC (gap propagated to entire SYN chain)
  • SRAL from 20190405T12:04:47 UTC to 20190405T12:29:45 UTC
  • OLC from 20190405T12:04:47 UTC to 20190405T12:14:43 UTC.

All Copernicus Sentinel-2A products related to orbit 19751 with sensing time between 06:50:06 and 07:52:24 UTC on 4 April are affected by a considerable geolocation inaccuracy due to a collision avoidance manoeuvre, which was executed between 06:23:05 and 08:22:17.
