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.

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.

An important new tool to combat climate change is now available. Using data from the Copernicus Sentinel-5P satellite, this new technology makes it possible to track and attribute methane emissions around the world. 

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.
