Objetivo - To make an inventory of the atmospheric pollution problems existing in Tunisia and in Algeria : the origin of the pollution, the nature of the pollutants, the geographical distribution of them;- To make an up to date bibliography and a preliminary laboratory work on the qualitative and quantitative detection of species chosen using the results of the inventory;- To determine the specifications of a station suitable for teledetection in the climatic, economic and social conditions of North Africa;- To set up the technical document necessary for the realisation of the LIDAR.- The final technical document describing the LIDAR station using both CW and pulsed laser diode source, which was the main aim of the project.- The final scientific document including the data on pollution, results on indoor measurements on ammonia and ozone.- One electronic device, made at FST and at LPPM with the industrial partner collaboration, for CW infra-red laser diode excitation source.- The conception of one electronic device, realised at CDTA and at LPPM with the industrial partner collaboration, for pulsed infra-red diode excitation source.- The setting up of an infra-red pulsed laser source using stimulated Raman emission of HD, excited par a Ti-Sa laser (almost ready) in LPPM.- The setting up of a LIDAR detection using a pulsed CO2 laser for monitoring hydrocarbures and ozone in Madrid district, at IP (almost ready).Follow upAfter the end of the contract, the collaboration between the group is still actively going on, especially in the field of personnel exchange :- Two Algerian engineers have spent some months in LPPM this year (1997) to achieve the electronic devices included in the LIDAR and to work on the stimulated Raman source;- A Tunisian engineer has spent some weeks in LPPM this year (1997) to work with J.-L. Duvent on the electronic acquisition system;- An Algerian engineer is at the moment in Madrid building up the telescope for far field teledetection;- A PhD student is working at the moment in Algiers on the teledetection of methane;- The second step, which is the realisation of the LIDAR station, has already started by the realisation of excitation sources, optical detection device and fast electronic for acquisition and analysis of data.Five partners (academic and industrial) were co-operating in the following tasks :- Updating all the information concerning the main atmospheric pollution problems in their countries, where it appeared that industrial and petrol production were the main sources of deterioration of the environment;- Bibliographic work concerning the data on the subject and the state of the art of the analytic methods of detection, and conducting preliminary experiments on the chosen species;- Determination of specifications of the teledetection station in co-operation between the Industrial LD and the other partners, using all the qualifications;- Elaboration of a final technical document;- Some main decisions for the construction of the LIDAR have been made during the processing of the project : the domain of wavelength are chosen in the near infra red, between 3u and 4u, and the first species to be detected is the methane CH4. The excitation sources are laser diodes excited by a pulsed or continuous power supply. For the laboratory experiments, a CO2 laser (IP) to detect O3 is used, and a Titanium-Sapphire pumped by a pulsed YAG (LPPM) is used to create by stimulated Raman scattering the 3.3u wavelength to detect CH4. Electronic devices have been realised in LPPM for the CW diode excitation source (for FST), and electronic devices have been designed in LPPM for the pulsed diode excitation (for CDTA); Programa(s) IC-AVICENNE - Avicenne Initiative (Science and technology cooperation with the Maghreb and the countries of the Mediterranean Basin), 1991- Tema(s) Data not available Convocatoria de propuestas Data not available Régimen de financiación CSC - Cost-sharing contracts Coordinador CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE Aportación de la UE Sin datos Dirección Rue Michel Ange 3 75794 PARIS Francia Ver en el mapa Enlaces Sitio web Opens in new window Coste total Sin datos Participantes (4) Ordenar alfabéticamente Ordenar por aportación de la UE Ampliar todo Contraer todo Centre de Développement des Technologies Avancées Argelia Aportación de la UE Sin datos Dirección 128,Chemin Mohamed Gacem El-Madania 16000 Alger Ver en el mapa Coste total Sin datos Laserdot Francia Aportación de la UE Sin datos Dirección Route de Nozay 91460 Marcoussis Ver en el mapa Coste total Sin datos Universidad Complutense de Madrid España Aportación de la UE Sin datos Dirección c/ Isaac Peral 28040 Madrid Ver en el mapa Coste total Sin datos Université de Tunis Túnez Aportación de la UE Sin datos Dirección Campus Universitaire 1060 Tunis Ver en el mapa Coste total Sin datos
