NDACC-France
Network for the Detection of Atmospheric Composition Change
The project
The NDACC (Network for Detection of Atmospheric Composition Change), formerly NDSC (Network for Detection of Stratospheric Change), is an international network for long-term monitoring of the stratosphere and the high troposphere established in 1991. Objectives include the detection of natural or anthropogenic changes in the atmospheric chemical composition and temperature, studies of interactions between atmospheric chemistry and climate, and long-term validation of similar measurements from available satellites. French activities are grouped in the Service d’Observation NDACC-France of CNRS (Centre National de la Recherche Scientifique)/INSU (Institut National des Sciences de l’Univers) coordinated nationally by OVSQ (Observatoire de l’université de Versailles). They are funded by several entities including CNRS/INSU, as well as CNES (Centre National des Etudes Spatiales), IPEV (Institut Paul-Emile Victor), the region of La Reunion, and several partner universities. The laboratories involved are : the LATMOS (Laboratoire, Atmosphères, Milieux, Observations Spatiales) located in Guyancourt and Paris, the Laboratoire d’Aérologie in Toulouse, the Laboratoire de l’Atmosphère et des Cyclones in La Reunion Island, the Laboratoire d’Optique Atmosphérique in Lille, the Groupe de Spectrométrie Moléculaire Atmosphérique of the université of Reims as well as collaborators outside of France including IASB (Institut d’Aéronomie Spatiale de Belgique) in Bruxelles (Belgium) and NOAA (National Oceanic and Atmospheric Administration) in Boulder (United States). The observations are performed in several locations worldwide: in metropolitan France at OHP (Observatoire de Haute Provence), OMP (Observatoire Midi-Pyrénées) located at the Centre de Recherches Atmosphériques in Lannemezan, and in Villeneuve d’Ascq ; in Antarctica at Dumont d’Urville and Concordia (Dôme C); at OPAR (Observatoire de Physique de l’Atmosphère de l’île de la Réunion) in the southern tropics in the Indian Ocean, at the ALOMAR observatory in Andoya (Norway) at the Arctic Circle, and in eight other stations : ScoresbySund (Greenland), Sodankyla (Finland), Salekhhard and Zhigansk (Siberia), Tarawa (Kiribati) in the Pacific Ocean, Bauru (Brazil), Kerguelen (southern Indian Ocean), and Rio Gallegos (southern Argentina).
Products available
The French teams contribute with varied observations including: temperature, ozone, and aerosol vertical profiles using lidar ; ozone profiles by radiosounding, ozone and NO2 columns using UV-Visible SAOZ spectrometers, ozone columns using Dobson instruments (including a NOAA instrument at OHP), measurements of ultraviolet solar radiation and ozone column using spectro-radiometers, water vapor profiles using microwave radiometers and Raman lidar, and measurements of CH4, HCl, HF, CO, N2O using FTIR spectrometer (IASB sensor, Reunion Island).
