A scheduled maintenance activity will take place on Sentinel Online on 21 April.

Due to an anomaly in the ground segment the Sentinel-5P data from the orbit 18127 to 18130 have not been acquired and will not be processed. Some NRT products data are available from orbits 18127 and 18130, related OFFL products may be generated with less measurements and reduced quality. Users are recommended to use this data with care.

We are pleased to announce that the Sentinel-1A and -1B Precise Orbit Files (AUX_POEORB products) coming from the Sentinel-1 Full Mission Reprocessing 2021 (FMR 2021) are available on the Copernicus Open Access Hub (see News story for further information about the FMR 2021).

Due to an issue occurred at Ground Segment level, the Near Real Time Copernicus Sentinel-3A OLC, SLSTR and SRAL Level 1 and Level2 products starting from around sensing time 10-04-2021 T 07:15:00 UTC to 09:00:00 UTC have been missed or degraded. Recovery in order to have a proper set of NTC data is on going.

Due to a network anomaly at ground station level occurred on the evening of 6 April and resolved on 7 April afternoon, users are informed that the generation of several Copernicus Sentinel-2A products from sensing orbit 30239 to 30248 and several Copernicus Sentinel-2B products from sensing orbit 21333 to 21339 is delayed.

We are pleased to announce that a Full Mission Reprocessing (FMR) of the Copernicus Sentinel-1A and -1B precise orbital products (AUX_POEORB) will be available in the upcoming days on the Copernicus Open Access Hub

We are pleased to announce the public release of the Copernicus Sentinel-3 SYNergy Aerosol Optical Depth AOD products processed in NTC timeliness. Information about the characterisation of the new products is available in the product notice document.

Users are informed that due to an anomaly of the EDRS acquisitions service occurred on 31st March and resolved in the morning of 1st April, the generation of a number of products issued from EDRS acquisitions is suffering delays.

Part of the Aquatic Ecosystem Analysis Bachelor Programme, European students gathered online from four different countries, to learn about Remote Sensing for Water Quality Monitoring over the Guadiana River catchment, a cross-border resource between Portugal and Spain, using Copernicus Sentinel-2 data.

Further to our previous announcement of 22 March 2021,we are pleased to confirm the operational deployment of the geometric refinement for Copernicus Sentinel-2 products on 30 March 2021.
