The ERC1 funded MAESTRO project aims to answer this question by addressing the following goals: As part of this project, an airborne field campaign will be organized to collect the observations needed to […]

ACTRIS-FR

ACTRIS-FR is the French component of ACTRIS-EU for the observation and exploration of aerosols, clouds and reactive gases and their interactions. ACTRIS is a distributed European research infrastructure supporting research […]

SAETTA

SAETTA (Suivi de l’Activité Electrique Tridimensionnelle Totale de l’Atmosphère) detects and localizes in three dimensions the electromagnetic radiation emitted by atmospheric discharges in the VHF 60-66 MHz band. It provides […]

METCLIM Lidars

Context: Lidar observations are the only means to reproduce highly resolved vertical profiles of key atmospheric parameters such as water vapour content, temperature, aerosols, and clouds. They also have great […]

Gewex Cloud Assesment Database

Scientific background Clouds cover about 70% of the Earth’s surface and play a dominant role in the energy and water cycle of our planet. Only satellite observations provide a continuous […]

IASI

Developed by CNES (Centre National d’Etudes Spatiales) in partnership with Eumetsat (EUropean organisation for the exploitation of METeorological SATellites), the IASI (Infrared Atmospheric Sounding Interferometer) instrument was designed for operational meteorology and for monitoring atmospheric chemistry and climate. IASI is a thermal infrared Fourier transform spectrometer that provides radiance spectra and derived atmospheric variables to feed operational weather forecasting centers, the Copernicus Services and the scientific community.

Megha-Tropiques

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.

POLDER/PARASOL

POLDER (POLarization and Directionality of the Earth’s Reflectances) instrument analyses the intensity and direction of light reflected by the Earth and its atmosphere, as well as its polarization, a physical characteristic describing how waves propagate. Such measurements reveal some interesting properties of clouds and aerosols, thereby telling us more about how they affect climate. Designed and developed by CNES, in close collaboration with the LOA atmospheric optics laboratory in Lille, the POLDER instrument is mainly dedicated to the study the of the clouds and aerosols properties, but it also provides valuable information on the directionality of terrestrial reflectances and on the ocean colour. It has been the first space instrument to provide global and systematic spectral, directional and polarization measurements of radiation reflected from the Earth and atmosphere.

ACTRIS

ACTRIS is a European research infrastructure that coordinates the acquisition and dissemination of measurements for the characterisation of ‘short-lived’ components of the atmosphere.The themes covered by this infrastructure are :  […]
