Abstract: The Monte Carlo method has been applied to the transfer of solar radiation through clouds with horizontal inhomogeneities which are assumed to consist of horizontally periodic striations. At a wave- length of ? = 0.55 µm ...

Abstract: An improved calibration method for a chopped pyrgeometer is presented. The chopped pyrgeometer is a system of two radiometers (target radiometer and reference radiometer) modulated by a common chopper. One radiometer ...

Abstract: Results are presented from a detailed case study of an Arctic stratus cloud over the Fram Strait that is based on aircraft measurements and model calculations. The measurements have been performed during MIZEX 1984 (Marginal ...

Abstract: A near-linear relationship is described between aerosol optical depth for Saharan dust over the eastern tropical Atlantic Ocean and radiance measured aboard the NOAA 3 satellite by the VHRR.

Abstract: A new type of pyrgeometer, which uses modulation of the atmospheric radiation by a mechanical chopper, has been built for the use of ground-based and airborne measurement of broadband infrared atmospheric irradiances. The ...

Abstract: During the intensive International Cirrus Experiment conducted over the North Sea during fall 1989, natural cirrus and contrail-induced cirrus were analyzed from in situ and remote sensing measurements (lidar and infrared ...
