A tool in the fight against climate change

 

The national network of ICOS Ecosystems Research European infrastructure, a scientific tool flagship of the fight against climate change and reducing greenhouse gas emissions (GHG) was officially opened September 18, 2015.

France with the CEAl’INRA, le CNRS (CETPIPSL , LMDLSCE  and ANDRA was behind the building of the ICOS infrastructure by 2008. The official launch of the Infrastructure European level (ERIC ICOS) with 8 signatory countries, including France and 9 countries pending integration partners in the device was held on September 18.

France has a recognized level of scientific excellence in the fields of observation and modeling covered by ICOS. She coordinated the preparation and infrastructure construction. It houses the European center in Saclay atmosphere and part of Central European ecosystems in Bordeaux. Thanks to the Grand National Loan (Equipex Infrastructure and future), it has built the National Ecosystems stations network (18) and Atmospheric (8) the largest network of ICOS. She also wears extensions Overseas (French Guiana, Reunion Island and Amsterdam) and therefore a major contributor of ICOS.

The European ICOS network includes 95 monitoring stations in operation, including 32 on continental ecosystems, crops, grasslands, forests, wetlands. Automated measurements are transmitted, processed and controlled by three thematic centers in France, Italy and Norway and distributed freely available through a central portal data (www.icos-cp.eu).

Terrestrial ecosystems are responsible for sequestering the equivalent of more than a quarter of greenhouse gas (GHG) emitted by humans into the atmosphere (5th Report of the IPCC). The futures maintaining sequestration of greenhouse gases by terrestrial ecosystems is very uncertain. This uncertainty makes it necessary to establish a precise observation of the cycle of greenhouse gases into the environment over the long term. The infrastructure allows for an accurate and verifiable information that provides information in real time on the evolution of the global environment, including climate and atmospheric greenhouse gas effect. This is, by continuously monitoring gas exchanges greenhouse with the atmosphere, understanding how ecosystems respond to this development.
