Some Results of Spectral and Radiative Measurements During IOP - 1996 in Tomsk

At present the problems of the radiation transfer theory in the cloudy atmosphere have not been completely developed. However, a series of problems is available, which can be solved only as a result of complex experimental measurements of spectral, radiation, thermodynamic, microphysical, and other characteristics of cloudiness. In particular, cloudiness is During the experiments carried out in fall 1996, we have a readily scattered and absorbed polydisperse system obtained more than 400 spectra of the direct solar radiation in characterized by an essential inhomogeneity both in vertical the 400 to 700 nm range, and more than 200 spectra of and in horizontal directions; cloudiness is also characterized scattered solar radiation. The values of the solar brightness by a variety of optical and microphysical parameters. Because outside the atmosphere are estimated based on the results of of this, the complex measurements in the free atmosphere are observations of direct solar radiation using a stellar solar of particular significance. photometer (on the basis of the “long Bouguer method”).
