Abstract: An experimental study using lidar has been made of possible resonance scattering from water vapor at 694.38 nm. This radiation was not detectable. An upper bound for the differential backscatter resonance cross section, ...

Abstract: The accuracy in the determination or the solar constant by means of the Langley method is strongly influenced by the spatial inhomogeneities of the atmospheric aerosol. Volcanos frequently inject aerosol into the upper ...

Abstract: Measurements by monostatic lidar have been performed in the laboratory and in the field of the linear depolarization ratios for hydrometeors. The depolarization ratios for water drops in the size range 10 to 2000 ? in ...

Abstract: A computational approach for the multiple backscattering from spherical cloud droplets for a collimated pulsed radar system has been developed, based on the geometry of the system. The radiative transfer relationships ...
