With Europe's tallest active volcano of 3325 metres frequently erupting, volcanology experts are using data from the Copernicus Sentinels to monitor the situation for environmental and safety impacts, since its various recent explosions.

Part of the Aquatic Ecosystem Analysis Bachelor Programme, European students gathered online from four different countries, to learn about Remote Sensing for Water Quality Monitoring over the Guadiana River catchment, a cross-border resource between Portugal and Spain, using Copernicus Sentinel-2 data.

The monitoring of frozen river break-ups at high latitudes is a daunting task, where hazards such as flooding and infrastructure damage can occur in mere days and are difficult to forecast— the monitoring from space of how river ice break-ups unfold and progress could help mitigation efforts, create data for reanalysis and aid hazard assessments.

On 6 February 2021, a huge windstorm from the Sahara reached large parts of the Alps and Pyrenees, giving the snow and surrounding area a sepia coloured nuance, and creating a Mars-like atmosphere—Copernicus Sentinel-3 caught it in real-time, adding to its ability of supplying aerosol estimates.

MAAP (Monitoring of the Amazon Project), a programme within the organisation Amazon Conservation, focuses on real-time monitoring of deforestation and fires. Copernicus Sentinel-5P data are a game changer in their work to monitor Amazon fires.

On the Romanian Danube sector in South-Eastern Europe, sand and ice banks can present difficulties for ships navigating these waters—Copernicus Sentinel satellite images are used by local authorities, to monitor navigation and manage traffic.

Over the past summers, the Alta Murgia National Park in Southern Italy faced a lack of information on wildfires for post-fire assessments-Copernicus Sentinel-2 data came into action, enabling the design and development of Rheticus® Wildfires by Planetek Italia: a geo-information service offering solutions.

Mozambique has some of the most climate-resilient coral ecosystems worldwide - and one of the world's most important reefs - Copernicus Sentinel-2 data are helping to assess where they are and what is happening to them over time.

On 30 October 2020, a powerful earthquake struck Turkey's western coast and the Greek island of Samos, causing extensive damage as well as casualties—the Copernicus Sentinel-1 mission was used to map the related co-seismic ground displacements within 24 hours, contributing to relief efforts.

A rainfall deficit in Argentina generated a forecast of a decrease in the production of winter crops as well as forage production this year, affecting the yielding of livestock in its central regions—data from the Copernicus Sentinel-1 mission are helping to create a monitoring system for such croplands.

California, Oregon and Washington State have been burning for over a month now, leaving most of the western United States under smoke—data from the Copernicus Sentinel-2, -3 and -5P missions are providing a wealth of complementary information, needed to monitor the blazes.

Four years ago, the Slovenian Company Sinergise Ltd triumphed at the 2016 Copernicus Masters Competition with its ground-breaking satellite image web service — the Sentinel Hub. This service revolutionises access to Earth observation satellite imagery, reducing from hours to mere seconds the time required to visualise and exploit data.

A team of researchers in Cyprus have been studying how to use Copernicus Sentinel and Landsat data together, to improve the domain of remote sensing archaeology.

Researchers from the University of Oslo have applied a technique to extract the detailed flow field of Khumbu icefall in the Nepalese mountains, from a large collection of Copernicus Sentinel-2 data—thus enhancing the capabilities of these data towards a reliable and consistent glacier mapping instrument.

In this video, expert interviewees explain how thanks to satellite images we can monitor the impact of human actions on the conservation of archaeological and heritage sites, such as illegal excavations and destruction in areas of conflict, as well as better understand the impact of natural events.

The recent development of MasTer tool – an InSAR automated Mass processing toolbox for multidimensional time series, is making a difference in the systematic and automatic use of Copernicus Sentinel-1 data for ground deformation monitoring.

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.

Until recently, the exploitation of Earth Observation in the coastal domain had been limited by the complication of obtaining the right satellite image—but now Copernicus Sentinel-2 data are making a difference.

River ice jams are a prime source of flood risk in cold regions. This recently occurred in Alberta, Canada, where the flooding of Fort McMurray resulted in the evacuation of the downtown district and in extensive damage. Copernicus Sentinels are lending a hand to monitor river ice conditions before ice jams affect towns and cities.

A new brochure featuring some of the highlights of our Sentinel Success Stories is now available and demonstrates just some of the successes of the Sentinels.
