The aerosol sprays they are small particles present in the atmosphere. They are responsible for the formation of clouds and, at the same time, contribute to the greenhouse effect and the heating climate.
The aerosol sprays they are naturally present in the atmosphere. They can come from forest fires or volcanic eruptions, for example, but also from the combustion of fuels fossils. Whether they are of human or natural origin, these fine particles are, among others, capable of promoting the effect of holes in the ozone layer.
They play a role in the formation of clouds, modifying their composition or their nature and thus participate in the greenhouse effect, as much or more as CO. Calypso, a satellite of Cones, has been observing them for 9 years in the hope of understanding precisely their impact. This equipment is capable of accurately measuring the characteristics of the different layers of the atmosphere.
The Cnes is a public establishment in charge of offering and conducting the space policy of France within Europe. Created in 1961, the Cones invent the satellite systems and launchers of tomorrow that respond to the needs of society. Cnes plays a key role in scene space nnational, European and international being a driving force, of innovation for the benefit of employment, and a center of specialization technique. In permanent relationship with the public powers and the scientific and industrial communities, it prepares and carries out program spatial innovative.
