Abstract: Pollutants (gaseous and aerosol) contained in urban atmospheres alter radiative fluxes at the surface.Numerous radiative models have been developed, and while few experimental data are available, results areoften contradictory. ...

Abstract: Simultaneous measurements of the vertical distribution on Rn-222, Aitken nuclei and small ions have been carried out in southwest France, several hundred kilometers from the Atlantic Ocean, between ground level and 6000 ...

Abstract: This study presents a method of obtaining the quantitative intensity of vertical diffusion during periods of atmospheric stability. This method associates the continuous measurement of radon concentration at ground level ...
