We are pleased to announce the upcoming start of the geometric refinement for Copernicus Sentinel-2 products. The goal of this evolution is to improve the multi-temporal co-registration and the absolute geolocation accuracy of the products, by using a Global Reference Image (GRI) as source of Ground Control Points (GCPs) to constrain the geometric model of the images.

Following the announcement on 8 March, please note that:

• Sentinel-1 orbit auxiliary files will be available at https://aux.sentinel1.eo.esa.int/ until 28 March 2021
• The reference for accessing the Sentinel-1 orbit files is on the Copernicus Sentinels POD Data Hub

Due to an issue occurring at PDGS level, the Near Real Time Copernicus Sentinel-3 SRAL NRT and STC Level 1 and Level 2 products starting from approximate sensing time 18:28 UTC on 18 March 2021 will be missed or delayed.

As a consequence of a contingency held at ground network level, the nominal availability of Copernicus Sentinel-2 Level-2A products was prevented on 13 March.

The monitoring of frozen river break-ups at high latitudes is a daunting task, where hazards such as flooding and infrastructure damage can occur in mere days and are difficult to forecast— the monitoring from space of how river ice break-ups unfold and progress could help mitigation efforts, create data for reanalysis and aid hazard assessments.

Following popular demand from the Sentinel-3 user community, ESA are now providing Copernicus Sentinel-3 SLSTR Level 3 composite products for the Land Surface Temperature (LST) Level 2 products. Daily and monthly composites are provided.

As previously reported, a major incident occurred on a data centre providing data access infrastructure services on 10 March 2021, which led to a temporary interruption of new data from Copernicus Sentinel-1 and Sentinel-3 and the temporary interruption of historical data access (from more than a year ago).

As previously reported, a major incident occurred on a data centre providing data access infrastructure services led to the temporal interruption of the publication of fresh Sentinel-1 and Sentinel-3 data on 10 March 2021 01:10 UTC.

An incident occurred on 10 March 2021 at 01:00 UTC on the infrastructure hosting the data access services.
