The complexity of the Earth system requires ingenious modelling strategies to reduce the related expense of simulations - usually at the cost of accuracy. Eradiate, a new, highly accurate and flexible radiative transfer model in the optical domain, will help generate reference data for instrument calibration.

The publishing of Copernicus Sentinel-3B OLCI L1 (OL_1_EFR, OL_1_ERR) and L2 (OL_2_LFR, OL_2_LRR) reprocessed data is approaching completion.

An infrastructure maintenance is planned on 8 July 2020 from 06:00 to 12:00 UTC on the Collaborative Data Hub Node 3.

A maintenance activity on the core infrastructure hosting the Data Hub services, involving the update of the network infrastructure, is planned on 7 July 2020 from 02:30 to 05:00 UTC.

We are pleased to announce the release of new processing baselines 2.66-A and 1.40-B for Copernicus Sentinel-3A and 3B concerning the following products and cut-dates:

• OL_2_LFR and OL_2_LRR, NRT/NTC, on 2020-06-23T08:00 UTC
• SY_2_SYN, STC/NTC , on 2020-06-23T08:00 UTC.

Due to a Copernicus Sentinel-3B SRAL instrument anomaly all the related user data are degraded since 17 June 2020 13:28 UTC.

This day—23 June 2020, marks five years of successful operations of the Sentinel-2A mission of the European Union's Copernicus Programme.

Copernicus Sentinel-2A was launched on 23 June 2015, followed by its twin on 7 March 2017, both delivering information for applications such as agriculture; land ecosystems monitoring; forests management; inland and coastal water quality monitoring; disasters mapping and civil security.

Due to a scheduled maintenance on 22 June on the PDGS infrastructure for Copernicus Sentinel-3A and Copernicus Sentinel-3B products belonging to sensing time window from 03:00 to 06:00 UTC could be delayed.
