ترجمة الملخص

Atmospheric aerosols play an important role in the earth's climate system. They are also the source of certain air pollution problems in urban areas. However, their influence on global climate change, as well as their chemical properties in urban areas, are still very poorly understood. Climate change is one of the greatest environmental challenges that our societies will have to face and will have to respond both globally and at regional scales through sustainable development policies such as the Earth Summits; COP21 (Paris 2015); COP20 (Lima 2014); COP19 (Warsaw 2013) and COP18 (Doha 2012). Even a small increase in the earth's average temperature would have important consequences for agriculture, forests and hydrological cycles, and for the biosphere. A precise description of the chemical composition of the atmosphere is now required to face many environmental challenges, whether on a global scale (climate change, oxidizing capacity of the troposphere, stratospheric ozone hole), regional (transboundary pollution) or local (industrial accident, urban air quality). In order to characterize these aerosols, We have cited CG / MS, CI, thermo-optics, AMS, XRF for the analysis of chemical properties; LIDAR, then SMPS and L’OPC for the physico-optical characterization.
