GRUAN is an international reference network of about thirty stations dedicated to the observation of key climatological variables between the surface and the stratosphere by radiosoundings. Several French organisations have been actively collaborating for 36 months to certify two major sites: a site in Ile-de-France comprising the Météo-France radiosonde station in Trappes and the SIRTA […]
ICOS (Integrated Carbon Observation System) is a European Research Infrastructure for measuring atmospheric concentrations of greenhouse gases and fluxes on ecosystems and the ocean. As the increase in greenhouse gases is the main cause of climate change, the interest of ICOS is to allow, in the long term, the monitoring of their sources and sinks. This monitoring will provide verification of emissions and sinks independent of fossil emission inventories and land use data. The ICOS infrastructure mobilises more than 500 researchers and engineers from 17 European countries; it is a key element of the European Research Infrastructure Roadmap (ESFRI) and constitutes a Very Large Research Instrument (TGIR) of the French national research strategy. The French part of ICOS is coordinated by the Laboratoire des Sciences du Climat et de l'Environnement (LSCE) which depends on CEA, CNRS, UVSQ and INRA.
aerosolsthe cloudsreactive trace gases (O3, NO2, NH3, C2H6…) The data mainly come from measurements carried out on site by remote sensing (photometers, lidars, radars, etc.) or by taking samples (mass spectrometers, nephelometers, etc.) but also from experiments carried out in atmospheric simulation chambers. It is also available at the national level under the name ACTRIS-FR. […]
The project The aim of the ARISE-FR project is to integrate observation and research activities on the atmospheric dynamics from the troposphere to the lower thermosphere in order to improve synergies, visibility and sustainability of the French infrastructures involved in this domain. It is based on the European research infrastructure project, ARISE (Atmospheric dynamics Research […]
The project EUROCHAMP-2020 aims at further integrating the most advanced European atmospheric simulation chambers into a world-class infrastructure for research and innovation. The project is composed by a coordinated set of networking activities, which deliver improved chamber operability across the infrastructure, as well as standard protocols for data generation and analysis. Trans-national access is provided […]
The project The atmospheric mercury compounds monitoring program GMOS-FR has been initiated thanks to the support of the EU FP7 GMOS (Global Mercury Observation System – 2010 to 2015) and the French Polar Institute IPEV (program GMOstral-1028 from 2012, still in progress). GMOS-FR is now also supported by GOS4M (Global Observation for Mercury), a GEO […]
The project INDAAF (International Network to study Deposition and Atmospheric composition in Africa) is a programme dedicated to the long-term monitoring of the atmospheric composition and of the atmospheric deposition fluxes in Africa. The objective is to document and understand the different steps of the life-time of gaseous and particulate species from their emission, transport […]
The project The NDACC (Network for Detection of Atmospheric Composition Change), formerly NDSC (Network for Detection of Stratospheric Change), is an international network for long-term monitoring of the stratosphere and the high troposphere established in 1991. Objectives include the detection of natural or anthropogenic changes in the atmospheric chemical composition and temperature, studies of interactions […]
