Atmospheric Chemistry Team ( Chimie de l'Atmosphère (CA) ) is studying the Earth Stratosphere and Troposphere as well as the martian Atmosphere.
1) The Stratosphere
Study of the mechanism related to the destruction of the ozon layer: nitrogen , bromine, chlorine dioxides and polar stratospheric clouds.
Long term monitoring of ozon, NO2 andPolar Stratospheric Clouds (PSC). SAOZ is recognized by the International Network NDSC (Network for Detection of Stratospheric Change).
The Ground-based SAOZ developped by Service d'Aéronomie are UV-Visible Spectrometers able to measure all year around vertical columns of O3, NO2 and PSC twice a day during sunrise and sunset by looking at the solar lights scattered at zenith.
The SAOZ Balloon instruments, light and robust, allow frequent measurements of O3, NO2, BrO, OClO, IO, aerosols and PSC vertical profiles in the Arctic, mid-latitudes and tropical regions.
Long Duration Balloons
- Infra-Red Montgolfier at the equator and in the Arctic in 1997, 1999 and 2000.
2) The Troposphere
Quality of Air ( O3, NO2, SO2, NO, HNO3, Hydrocarbures ).
SANOA is a long path UV-Visible spectrometer to monitor continuously the atmospheric pollution.
- Field campains.
3) Planetary Atmospheres
Study of clouds and aerosols of the Martian atmosphere from small ground-based stations.
