Sentinel-1 provides support in Taiwan's earthquake

22 February 2018

The Sentinel-1 satellites of Europe's Copernicus Programme are being used to quantify the surface deformation of the disaster area around the Hualien earthquake.

Copernicus Sentinel-3 soon to be in tandem

08 February 2018

The Sentinel-3B satellite scheduled for launch this spring, will be flying 30 seconds apart from its twin, Sentinel-3A, during the commissioning phase. This temporary tandem arrangement is to obtain better cross-calibration between instruments, thus reducing uncertainties in the multi-satellite time series and ensuring an overall high data quality.

Sentinels monitor volcanic Mount Agung

25 January 2018

Observations by the Copernicus Sentinel satellites over Mount Agung in Bali, are helping scientists to monitor the ongoing eruption and identify any changes in magma pressure, possibly indicating whether a bigger eruption could occur.

Sentinel-2 exceeds expectations

18 January 2018

Discover more about our planet with the Earth from Space video programme. This special edition celebrates two years of operating the Copernicus Sentinel-2 mission.

Copernicus Sentinel-3 offers safer navigation at sea

11 January 2018

Wave information is crucial for people working at sea, to be able to navigate and operate safely. A new product based on satellite altimeter data detailing ‘Significant Wave Height' now enables this.

Sentinel-3 helps water-quality monitoring

21 December 2017

Monitoring large, remote bodies of water is logistically challenging, time consuming and expensive. Responding quickly to events that pose a risk to human health has been almost impossible, given the size of some lakes and seas. An innovative satellite data service is now able to change things around.

Sentinel-1 focuses on floods

14 December 2017

Carrying advanced radar instruments, which can image Earth's surface regardless of the weather and darkness, the Copernicus Sentinel-1 mission is bringing new insight into the aftermath of heavy rains and hurricanes.

Sentinels provide valuable support to International Disasters Charter

07 December 2017

The Copernicus Sentinel satellites have proven to be invaluable for various activations of the International Disasters Charter.

Sentinels bring wildfires into focus

16 November 2017

In October 2017, a series of wildfires broke out in northern California, killing many and burning thousands of acres of land. Satellite imagery and particular data processing techniques are being used to help map the extent of the damage.

Three years of success with Sentinel-1

09 November 2017

Discover more about our planet with the Earth from Space video programme. This special edition celebrates three years of successful operations of the Copernicus Sentinel-1 constellation.

Sentinels on call for the CEMS

02 November 2017

Between May and September this year, the Copernicus Emergency Management Service was activated more than ever, with many users needing its rapid mapping products to help respond to a range of environmental disasters.

ESA's Optics Lab runs tests for the EU Copernicus Sentinel-5P payload

12 October 2017

ESA's Directorate of Technology, Engineering and Quality, equipped with a suite of specialised laboratories and expert personnel, applied their expertise to help verify Sentinel-5P's air-monitoring instrument would perform as planned.

An eye on ocean currents with Sentinel-3

05 October 2017

Discover more about our planet with the Earth from Space video programme. In this special edition, senior scientist at France's Collecte Localisation Satellites, Marie-Hélène Rio, joins the show to discuss how data on ocean surface currents by the Sentinel-3 satellite mission are used by people working at sea.
