Abstract: The e-type effect on the water vapor continuum, suggested by Bignell's laboratory experiments, is investigated in the atmospheric extinction spectrum of the sun between 8 and 13 µm. A classification of atmospheres in terms ...

Abstract: Results of measurements of the monochromatic optical thickness (in the 0.65?13.5 µm wavelength region) of some thin clouds are reported. The observed wavelength patterns are discussed in terms of the optical properties of ...

Abstract: Measurements of the monochromatic atmospheric extinction of solar radiation (in the 0.65?13.5 µm wavelength interval) in the Po Valley and neighboring mountainous areas show the occurrence during the morning (after the ...

Abstract: The transformation of airborne SO2 into SO4? taking place in a polluted urban atmosphere has been investigated in terms of the equilibrium of the system composed of SO2, liquid water and NH3. The procedure used for selecting, ...

Abstract: The optical thickness a(?) of atmospheric particulate matter has been investigated in a near infrared wavelength interval. The instrument (a monochromator with a Newtonian telescope) was located at 1100 m MSL on the Appennine ...
