Stratospheric background aerosol and polar cloud observations by laser backscattersonde within the framework of the European project "Stratospheric Regular Sounding"
International audience The Stratospheric Regular Sounding project was planned to measure regularly the vertical profiles of several tracers like ozone, water vapor, NO x , ClO x and BrO x radicals, aerosol, pressure and temperature, at three latitudes, to discriminate between the transport and photo...
