TerrainRadiationSimple Class Reference

Simple guess of terrain reflected radiation. For each cell of the domain, a sky view factor is computed over 32 sectors and a 500m distance (see for example Faron S. Anslow, Steven Hostetler, William R. Bidlake, and Peter U. Clark, "Distributed energy balance modeling of South Cascade Glacier, Washington and assessment of model uncertainty", Journal of Geophysical Research, vol. 113, 2008). Then, for each cell of the domain, this view factor is transformed into a terrain view factor, multiplied by the albedo of the current cell and multiplied by the sum of the direct and diffuse radiation for the current cell. This is considered to be an approximation of the short wave radiation rewflected by the surroundings of the current cell. More...

Detailed Description

Simple guess of terrain reflected radiation. For each cell of the domain, a sky view factor is computed over 32 sectors and a 500m distance (see for example Faron S. Anslow, Steven Hostetler, William R. Bidlake, and Peter U. Clark, "Distributed energy balance modeling of South Cascade Glacier, Washington and assessment of model uncertainty", Journal of Geophysical Research, vol. 113, 2008). Then, for each cell of the domain, this view factor is transformed into a terrain view factor, multiplied by the albedo of the current cell and multiplied by the sum of the direct and diffuse radiation for the current cell. This is considered to be an approximation of the short wave radiation rewflected by the surroundings of the current cell.
