Determination of the macroscopic optical properties of snow based on exact morphology and direct pore-level heat transfer modeling... The effect of simplifying the snow microstructure and/or the radiative transfer model is elucidated by comparing our results to (i) a homogenized radiation model and considering a particulate medium made of optical equivalent grain size spheres (DISORT), or (ii) a multiphase radiation model considering a packed bed of identical overlapping semi-transparent spheres....
Remote sens. environ. 44:231-238 (1993) estimating snow grain size using aviris data... reflec-tance curves were each fit using a nonlinear least-squares technique which provided a means of trans-forming surface reflectance in each A VIRIS image to optically equivalent grain size on a per-pixel basis....
Estimation of snow water equivalence using sir-c/x-sar, part i: inferring snow density and subsurface properties... With these relationships, snow depth and optical equivalent grain size can be estimated from SIR-C/X-SAR measurements....
The origin of "rare earth" texture development in extruded mg-based alloys and its effect on tensile ductility... When these alloys are compared at equivalent grain size, the La- and Gd-containing alloys show the best ductilities....
