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.

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.

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 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.

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.

For about 30 years now, ESA satellites have been cruising some 800 km above our heads, collecting information about our planet—but why are older missions still so fundamental today?

Researchers of a Swiss company are testing Copernicus Sentinel-1 data to better calibrate the Enhanced SAR Vegetation Index (ESVI) for drought conditions, which could help insurance plans for farmers.

Sentinel-2 is part of the family of EU-owned satellites, which are developed and operated in the context of Copernicus – the European Union's Earth Observation and Monitoring Programme.

On 17 February 2018, the Sentinel-2 mission reached the 5-day global revisit periodicity, thus fully exploiting the two satellite units of the constellation.

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.

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.

Nearly 100 young scientists from 30 countries recently gathered at the Szent István University in Hungary, to attend a training course on land applications using satellite data and tools.

A low Earth-orbiting satellite, the Copernicus Sentinel-5 Precursor (Sentinel-5P) mission is dedicated to monitoring the composition of the atmosphere. Its data will be used largely by the Copernicus Atmosphere Monitoring Service. The mission will deliver information to monitor air quality, stratospheric ozone and will also be used for climate variables monitoring, and support European policy-making.

'Sentinel Stories' is presented by Malì Cecere. Professor Andreas Kääb of the University of Oslo describes his work with data from the Copernicus Sentinel satellites and what sort of benefits these bring to him and his team.

Dr Marie-Hélène Rio is a scientist from CLS, a subsidiary of the French Space agency CNES. She is responsible for developing and merging new algorithms to exploit Sentinel-3 data.

Steffen Dransfeld is in charge of the quality of the data from the Ocean and Land Colour Instrument (OLCI) and Sea and Land Surface Temperature Radiometer (SLSTR) instruments on Sentinel-3.

Sentinel-3 is part of the family of EU-owned satellites that are developed and operated in the context of Copernicus, the largest environmental monitoring programme in the world.

Today we are interviewing ESA's Philippe Goryl, who is responsible for leading the data quality managers of the various Sentinel missions.
