Shading parameter files

There are two types of shading parameter files that need to be specified when Shading = TRUE:

1. Shadow map files
2. Skyview file

Shadow map files

Required:

Required when Shading = TRUE.

Read by:

InitNewMonth()

Format:

2D Matrix

Purpose:

Contains a shading factor for every cell in the basin for each month. NOTE: This is a compound grid, with one shading factor for every timestep of the day (e.g., 8 sequential grids for a 3 hour timestep input). Shading factors vary from 0-255.

Comments:

File names are expected to be of the format:
<shading data path>.xx.<shading data extension>,
where xx is a 2-digit integer inidicating the month (use a leading zero for number smaller than 10)

Details:

If the format is BIN or BYTESWAP, then an unsigned char should be used.

If the format is NetCDF, then NC_CHAR should be used and the variable name in the NetCDF file should be Shade.Factor.

The shadow map files are masked based on the content of the mask file.

Skyview file

Required:

Required when Shading = TRUE.

Read by:

InitShadeMap()

Format:

2D Matrix

Purpose:

Contains the sky view factor for every individual grid cell in the basin.

Comments:

Details:

If the format is BIN or BYTESWAP, then a float should be used.

If the format is NetCDF, then NC_FLOAT should be used and the variable name in the NetCDF file should be SkyView.Factor

The skyview file is masked based on the content of the mask file.
