EUFAR (EUropean Facility for Airborne Research) is a European project for the integration of airborne research infrastructures dedicated to European scientists specialising in the fields of the environment and Earth sciences. The EUFAR community gathers 1900 members (partners, experts, users, etc.) and the current contract is made up of 24 legal entities including 12 operators. […]

ICOS – National Observation Service ICOS France Atmosphere (SIFA)

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.


The main goal of ECCAD (Emissions of atmospheric Compounds and Compilation of Ancillary Data) is to provide scientific and policy users with datasets of surface emissions of atmospheric compounds, and ancillary data needed to estimate or quantify the surface emissions. ECCAD provides the emissions of major atmospheric compounds like carbon dioxide, carbon monoxide, methane, nitrogen […]

GEISA : spectroscopic database

The project Since over three decades, the ARA (Atmospheric Radiation Analysis) group at LMD (Laboratoire de Météorologie Dynamique, France) has developed GEISA (Gestion et Etude des Informations Spectroscopiques Atmosphériques: Management and Study of Atmospheric Spectroscopic Information), a computer accessible database system [Chédin et al. (1982), Husson et al. (1992), Jacquinet-Husson et al. (1999, 2005, 2008, […]


BAOBAB/AMMA is an international programme that studies the West African monsoon, its variability and its links with socio-economic aspects. Its objectives are to improve our understanding of the monsoon and its impact on the physical, chemical and biological environment on a regional and global scale, to provide the basic scientific knowledge to establish the links […]


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 balloon data The French Space Agency (CNES) has been supporting scientific ballooning since its establishment, particularly in atmospheric science measurements, currently launching about 50 balloons a year. Balloon platforms offer excellent opportunities for scientific exploration, particularly for atmospheric observations that look through the atmosphere, and for astrophysical observations from above the atmosphere. To conduct […]


Megha-Tropiques is a space mission jointly managed by the space agencies CNES and ISRO. This mission is designed to study the convective systems of the atmosphere and more particularly the analysis of the water cycle through the transport and distribution of water vapor, the life cycle of convective systems and energy exchanges in the equatorial belt. The tropical zones are those where the most important energy exchanges occur: radiative exchanges, latent heat exchanges, transport of constituents and energy through dynamic processes. The challenge is therefore to increase knowledge of hydrological and energy processes in the tropics and their influence on the global circulation of the atmosphere, that the oceans, and climatic variations.


The Project The Mediterranean basin is one of the most sensitive region to global changes. It’s also one of the richest regions in terms of culture, natural resources, geopolitics and biodiversity. These issues justify a large mobilization of researchers, stakeholders, industries,… to address the question of the livability of the Mediterranean region by the end […]



The project The project-based structure of IUPAC makes Task Groups a key mode for implementation of the IUPAC mandate to enhance and improve communication worldwide among scientists in the chemical sciences. The Task Group Chair is responsible for the implementation of the project and, subject to approval by the Division Committee, for the appointment of […]
