Apply a shading mask to the Incoming or Reflected Short Wave Radiation A shading mask that is either computed from the DEM or read from a separate file will be applied to the radiation and combined with the radiation splitting model in order to properly compute the shading effects on the measurement point. This mask will be linearly interpolated between the provided points in order to be applied to the true sun position.
When providing thge shading mask in a separate file, the same mask will be applied to all stations. It simply need to contain the horizon elevation (in deg.) as a function of azimuth (in deg.):
Then the filter is declared with the file name containing the horizon mask as argument:
If no arguments are provided, then it will compute the mask from the Digital Elevation Model. In such as case, a DEM must be declared in the [Input] section and must contain the stations of interest as a mask will be computed for each station. Please make sure that the extend of the DEM is appropriate to correctly compute the shading effects!
