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.
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.

Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic. Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet – causing a ‘mini-hole’ in the ozone layer.
Copernicus Sentinel-3B OLCI L1 (OL_1_EFR, OL_1_ERR) and L2 (OL_2_LFR, OL_2_LRR) reprocessed data will be soon available on the Open Access Hub. The time period covered by the reprocessing activity includes the commissioning phase of Sentinel-3B, therefore part of these products are newly published on the data hub and are going to cover a gap of several months of data.

Due to a Copernicus Sentinel-3B SLSTR instrument special operation scheduled on 30 March, the IR channels may be degraded during the overall duration of the maintenance lasting 3 hours and 22 minutes. As a consequence of that all the SLSTR/SYN user products may be degraded from UTC sensing time 10:50 to 14:12 on 30 March.
