The Sentinel-5P mission of the European Union's Copernicus Programme has become a game-changer for monitoring our atmosphere while being one of the most important sources of data for the Copernicus Atmosphere Monitoring Service.

Climate Change and human activity will have an increasingly dramatic effect on coastal zone management in the foreseeable future—but data from the Copernicus Sentinel missions have the potential to add enormous value to coastal zone management solutions.

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.

Until recently, the exploitation of Earth Observation in the marine domain was somewhat limited, due to poor spatial resolutions and long revisit times, often extending to months or years— today, Copernicus Sentinel data and the development of multispectral techniques are bringing significant advantages in monitoring marine debris.

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.

A recent study was carried out comparing NASA's FIRMS data with Copernicus Sentinel data, resulting in Copernicus Sentinel-1 data particularly detecting wildfires in Australia.

Featuring how satellite data, such as those from the Copernicus Sentinel-1 and -2 missions, are being used to monitor infrastructure systems in urban areas.

Australia has been struggling with severe bushfires for months now, and while experts are using all the satellite data they can to help monitor the situation, new products from the Copernicus Sentinel-3 mission will provide Fire Radiative Power information and aerosol parameters.

While two explorers were having problems cruising the ice across the North Pole on skies, due to bad weather and complications with equipment, the Copernicus Sentinel-1 satellites lent a hand to guide rescuers through the maze of ice and water to save the day.

Featuring how the Sentinel missions of the European Union's Copernicus programme, particularly Sentinel-1, have become a game-changer to the Danish Meteorological Institute's Ice Service and to the project – Automated Sea Ice Products – creating a robust, automated sea ice information service, solving the main needs of Arctic marine users.

Italy has been victim of days-long flooding and high-tides, owing to the severe weather of the past weeks. Although forecasts do not promise an improvement just yet, the Copernicus Sentinels have teamed up to help monitor the situation.

The Copernicus Sentinel family is almost fully composed of twins. Because of their large field of view, these twins see many locations in the High Arctic two or more times per day, with time lags of minutes to hours. In this resulting time-lapse, satellite imagery of a range of short-lived movements on Earth's surface can be detected.

On 11 October, some 95 km from the Saudi city of Jeddah, an Iranian-owned oil tanker was damaged, resulting in the loss of oil in the Red Sea. The Copernicus Sentinels are being used to monitor the resulting oil spill.

Seasonal wetlands are common in Mediterranean climates. They flood during rainy seasons in autumn and winter and dry-up in summer. Precipitation changes in these areas have profound effects on the dynamics of wetlands, affecting plants and animals that inhabit them. These wetlands can suffer changes in their hydrology, becoming transformed into permanent lakes or completely drying-up—but Copernicus Sentinels are making a difference.

A Danish R&D project is developing an automatic sea ice product service, which can meet the increased demands for better and more timely sea ice information, using the extensive amount of free and available data from the Copernicus Sentinel satellites, along with novel machine learning techniques for satellite data fusion and sea-ice information retrieval.

Featuring ECOPOTENTIAL, a European funded project that focuses on a set of internationally recognised protected areas, this video describes how the unprecedented availability of satellite data allow scientists to understand large scale changes in our environment and how best to protect it. 

Tracking spatio-temporal variations in flooded areas of wetlands is not an easy task, especially when they are characterised by a dense cover of emergent vegetation. Researchers in France developed a tool to monitor water in seasonal wetlands using Copernicus Sentinel-2 data, which exceed the performance of existing water indices.

The identification and location of groundwater‐dependent ecosystems are the first move in protecting and managing them. Such identifications are challenging where the surface signs of groundwater are not obvious. Copernicus Sentinel-2 data are lending a hand in establishing these ecosystems.

Dormant since 1924, the Raikoke Volcano in the Kuril Island chain, near the Kamchatka Peninsula in Russia, recently awoke. Data from the Copernicus Sentinel-5P and Sentinel-3 satellites are giving vital information on its aftermath.
