GMES overview


 
GMES - Observing our planet for a safer world
 
As the most ambitious Earth observation programme to date, Global Monitoring for Environment and Security (GMES) will provide, accurate, timely and easily accessible information to improve the management of the environment, understand and mitigate the effects of climate change and ensure civil security.
 
This ambitious Earth observation programme is headed by the European Commission (EC) in partnership with the European Space Agency (ESA) and the European Environment Agency (EEA).

ESA coordinates the delivery of data from upwards of 30 satellites and the EEA is responsible for data from airborne and ground sensors, while the EC, acting on behalf of the European Union, is responsible for the overall initiative, setting requirements and managing the services.

Managed by ESA, the Space Component is in its pre-operational stage, serving users with satellite data currently available through the GMES Contributing Missions at national, European and international levels. GMES will become operational after launch of the first Sentinel mission.

ESA is developing five families of Sentinel missions specifically for GMES, the first of which is scheduled to launch in 2013. The Sentinels will provide a unique set of observations for GMES, starting with the all-weather, day and night radar images from Sentinel-1 to be used for land and ocean services.

Sentinel-2 will deliver high-resolution optical images for land services and Sentinel-3 will provide data for services relevant to the ocean and land. Sentinel-4 and Sentinel-5 will provide data for atmospheric composition monitoring from geostationary and polar orbits, respectively.

The ground segment, facilitating access to Sentinel and Contributing Mission data, completes the GMES Space Component.

The Space Component forms the European contribution to the worldwide Global Earth Observation System of Systems (GEOSS).

The In situ Component is managed by the European Environment Agency and focuses on data acquired by a multitude of sensors on the ground, at sea or in the air. These data come from European and non-European organisations,

GMES provides a unified system through which vast amounts of data, acquired from space and from a multitude of in-situ sensors, are fed into a range of thematic information services designed to benefit the environment, the way we live, humanitarian needs, and support effective policy-making for a more sustainable future.

These services fall into six main categories: services for land management, services for the marine environment, services relating to the atmosphere, services to aid emergency response, services associated with security and services relating to climate change.

In essence, GMES will help shape the future of our planet for the benefit of all. ESA is contributing by providing a proven framework for the development of operational systems on behalf of the user community, paving the way for investment in future generation systems. ESA is exploiting its 30 years of expertise in space programme development and management to contribute to the success of GMES.
