GMES - video news release
Relying largely on satellite data, the Global Monitoring for Environment and Security (GMES) programme will provide accurate and timely data to better manage the environment, understand and mitigate the effects of climate change and ensure civil security.
ESA is responsible for the Space Component of GMES. It will provide continuous, accurate satellite data from Earth observation satellites, like Envisat and ERS. As part of the GMES programme, ESA is also developing, building and launching a new series of Earth monitoring satellites called Sentinels. The Sentinels are five families of satellites that will monitor the land, oceans, ice and atmosphere for markers of environmental change. Data from the Sentinel satellites as well as other ESA and non-ESA missions contributing to GMES will be combined with measurements taken on Earth. As changes in parameters such as air quality and ocean height are recorded over time, legislation can be put in place to tackle issues such as flooding, deforestation and drought.
