Related to the quality degradation of Copernicus Sentinel-5P data announced in the related news, the parameter qa_value for filtering the data, as recommended in the Product Readme Files, will not remove the data with degraded quality.

A change has been made in the time duration of the Copernicus Sentinel-3A/3B SLSTR L2 NTC user products. The new Copernicus Sentinel-3 Land PDGS Product Units Configuration document describes the configuration applied for the generation of the products at Land PDGS.

Last February, Argentina was struck with a severe storm that caused floods and damage. Data from the Copernicus Sentinel-1 mission helped to map the event, in ways which could assist crop insurers with occurred losses.

Due to an issue (and still ongoing) at Ground Station level on 20 April 2020:

SRAL STC Copernicus Sentinel-3A and -3B data starting from sensing time (UT) 09:24:01 to 22:14:30 on 21 April 2020 will be delayed.

Due to a ground segment anomaly affecting irradiance measurements used in the processing of several orbits of data, the a number of Copernicus Sentinel-5P products have reduced quality and users are recommended to use this data with care.

Further analyses are showing the continued low levels of nitrogen dioxide concentrations across Europe – coinciding with lockdown measures implemented to stop the spread of the coronavirus. New data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, show some cities seeing levels fall by 45—50% compared to the same period last year. 

Some Copernicus Sentinel-2A planned acquisitions have been lost due to a collision avoidance manoeuvre executed on 12 and 13 April.

Due to an issue at Ground Station level on 14 April 2020, some Copernicus Sentinel-3 data is missing.

The Magra reservoir in Alentejo, Portugal, became the test site for Aquatic Ecosystem Analysis students, learning to use remote sensing to monitor and possibly forecast algae blooms.

Due to a Copernicus Sentinel-3B spacecraft manoeuvre scheduled on 8 April  reduced data quality is expected for all the SRAL and SLSTR user products in the following UTC sensing time interval:

• SRAL from 11:18 to 11:52.
• SLSTR from 11:08 to 13:39.
