“…All the polar plots of HDRF in Fig. 4 show that the snow is forward scattering with values peaking at the top of the plots, in agreement with Kuhn (1985), Dozier et al (1988), Warren et al (1998), Leroux et al (1999), Aoki and Fukabori (2000), Painter and Dozier (2004), Li and Zhou (2004), Peltoniemi et al (2005), and Dumont et al (2010). The forward scattering pattern is most clear in sites B, C and D where the forward scattering peak occurs at zenith angles N 55°and azimuth angles ± 45°of 0°.…”

“…BRDF of snow was additionally determined under laboratory conditions (Dumont et al, 2010) and through modelling (e.g. Dozier et al, 1988;Leroux, Lenoble, Brogniez, Hovenier, & De Haan, 1999).…”

“…Both assumed that ice particles with internally mixed soot impurities of 0.2 ppmw and 0.5 ppmw in mass concentration, and externally mixed dust par- ticles as in the Dust-Only model. For the refractive indices of soot-contaminated ice particles, we averaged the refractive indices for ice and soot with the weight of the volume fraction of each component (Choudhury et al 1981;Leroux et al 1999). The soot aerosol particles, which have very small terminal velocity due to their small mean radius and density, seem rarely to contribute to the dry deposition through the gravitational settling and thus should be brought into the snow mainly through the wet deposition during snowfall.…”

We observed broadband snow albedos in the visible and the near infrared spectral regions with snow pit works of several-day intervals, during the winters of 2001/2002 and 2002/2003 at Shinjo, Japan. We examined the dependence of albedos on snow grain size and on concentration of snow impurities, comparing observations and theoretical calculations using a radiative transfer model for atmosphere-snow system. The comparisons revealed that the snow was contaminated by strong absorptive impurities such as soot additional to moderate absorptive impurities such as mineral dust. Snow albedo reduction after snowfalls (snow aging effect on albedo) observed in both spectral regions corresponded to the growth tendency of snow grains and the increasing concentration of snow impurities with elapsed time after snowfalls. Measurement of the atmospheric aerosols above the snow surface using a laser optical particle counter suggested that wet deposition of atmospheric aerosols caused snow impurities of more than 1 ppmw in mass concentration.

“…In such a case the adding-doubling method can be used, with or without asymptotic fitting [cf. Jafolla et al 1997; Leroux et al, 1999;Li, 1982], but for a semi-infinite layer one can also make use of Ambarzumian's nonlinear integral equation [See Sobolev, 1972, and Problem P5.7], using an iterative technique [cf. Dlugach and Yanovitskij, 1974;De Rooij, 1985].…”

In this paper we present an algorithm for the construction of the superoptimal circulant\ud preconditioner for a two-level Toeplitz linear system. The algorithm is fast, in the sense that it operates in FFT time. Numerical results are given to assess its performance when applied\ud to the solution of two-level Toeplitz systems by the conjugate gradient method, compared with the Strang and optimal circulant preconditioners
