Abstract: Recent experimental results indicate that little or no solid ammonium sulfate is present in background stratospheric aerosols. Other results allow straightforward calculation of sulfuric acid/water droplet properties ...

Abstract: The slant-path (or zenith-angle scanning) lidar technique is used to measure boundary-layer optical depths for ten different times during a single day. For the range of optical depths encountered (0.03?0.14 at 0.69 ?m ...

Abstract: Fifteen lidar observations of the stratosphere aerosol were made between February and November 1975. All observations revealed the greatly increased particulate backscattering that followed the eruption of the volcano Fuego ...

Abstract: A network of 13 sodars (acoustic radars) was operated in the San Francisco Bay Area for 2.5 months of the 1976 smog season. The goal was to produce a data base on time-dependent mixing depth and stability patterns for input ...

Abstract: By analysing two sets of atmospheric solar measurements, Laulainen and Taylor conclude that conventional Volz sunphotometry is subject to considerable error arising from apparent day-to-day variation in J0, the zero-airmass ...

Abstract: Several analytical models of the radiative effects of aerosol layers on global climate provide the common result that the critical value (?c) of the ratio (?) of aerosol layer absorption to hemispheric backscattering is ...

Abstract: Measurements are presented of the wavelength dependence of the aerosol absorption coefficient taken during the Tropical Aerosol Radiative Forcing Observational Experiment (TARFOX) over the northern Atlantic. The data show ...

Abstract: Although continental-scale plumes of Asian dust and pollution reduce the amount of solar radiation reaching the earth's surface and perturb the chemistry of the atmosphere, our ability to quantify these effects has been ...
