Sets the angular grids for the calculation of radiation fluxes.

This method sets the angular grids for the radiation fluxes type calculations and calculates the integration weights za_grid_weights for the zenith angle integration. For down- und up-looking geometries it suffices to use the default values of N_za_grid and N_aa_grid. From N_aa_grid an equally spaced grid is created and stored in the WSV aa_grid.

Depending on the desired za_grid_type za_grid will be equally spaced (‘linear’) or unequally (‘linear_mu’,’double_gauss’) Important, N_za_grid must be an even number because for the integration over each hemisphere N_za_grid / 2 zenith angles are needed.

Possible zenith angle grid types are:

  • double_gauss: The zenith grid and the integration weights are set according to a gauss-legendre integration for each hemispheres.

  • linear: Equally space grid between 0 deg and 180 deg including the poles

  • linear_mu: Similar to ‘linear’ but equally spaced for cos(180 deg) to cos(0 deg), which results a unequally spaced angular grid
