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 […]


Over past years CNRM has developed with support from AERIS/ICARE the AERUS-GEO suite of Aerosols and Surface properties products ( Initially aimed at providing a daily averaged Aerosol Optical Depth (AOD) from SEVIRI sensors aboard the MSG satelliteseries, the project is now about to provide retrievals of aerosol properties at 15-min intervals thanks to the new i-AERUS-GEO algorithm (currently under validation).


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 IAGOS (In-service Aircraft for a Global Observing System) is an European Research Infrastructure (ESFRI Roadmap 2006) conducting global longterm observations of atmospheric composition (reactives and greenhouse gases, aerosols, cloud particles) on a fleet of commercial aircraft of international operating airlines. IAGOS is an CNRS-INSU Observation Service since 1994 and a CNRS Research Infrastructure […]


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 “ReOBS” project aims to create a multi-parameter dataset with advanced quality control in a format that can be easily exploited by the scientific community for the study and understanding of climatic variables on a regional scale. The netcdf format has been chosen in order to provide the data but also the associated metadata following […]



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 […]

GIRAFE reGIonal ReAl time Fire plumEs Presentation GIRAFE is a software which provides forecasts of plumes trajectories. Trajectories are calculated using lagrangian dispertion model FLEXPART and ECMWF meteorological fields. GIRAFE uses fire detections of MODIS satellite in order to predict plumes trajectories, or MACC satellite data. At the moment two versions of GIRAFE exists : GIRAFE-MODIS : MODIS (Moderate Resolution Imaging […] - - -
