cloud_fieldsCalc
Calculate ext_mat, abs_vec for all points inside the cloudbox for one propagation direction. sca_vec can be obtained from the workspace variable doit_scat_field. As we need the average for each layer, it makes sense to calculte the coefficients once and store them in an array instead of calculating at each point the coefficient of the point above and the point below.

This function calculates the radiation field along a propagation path step for specified zenith direction and pressure level. This function is used in the sequential update and called inside a loop over the pressure grid. In the function the intersection point of the propagation path with the next layer is calculated and all atmospheric properties are interpolated an the intersection point. Then a radiative transfer step is performed.

rte_step_doit
Solves monochromatic VRTE for an atmospheric slab with constant conditions.
The function can be used for cloudbox calculations.
The function is best explained by considering a homogenous layer. That is, the physical conditions inside the layer are constant. In reality they are not constant, so in practical all coefficients have to be averaged before calling this function. Total extinction and absorption inside the layer are described by ext_mat_av* and abs_vec_av respectively, the blackbdody radiation of the layer is given by rte_planck_value and the propagation path length through the layer is lstep.
There is an additional scattering source term in the VRTE, the scattering integral term. For this function a constant scattering term is assumed. The radiative transfer step is only a part the iterative solution of the scattering problem, for more information consider AUG. In the clearsky case this variable has to be set to 0.
When calling the function, the vector stokes_vec shall contain the Stokes vector for the incoming radiation. The function returns this vector, then containing the outgoing radiation on the other side of the layer.
The function performs the calculations differently depending on the conditions to improve the speed. There are three cases:
stokes_vec | Input/Output: A Stokes vector. |
trans_mat | Output: Transmission matrix of slab. |
ext_mat_av | Input: Averaged extinction matrix. |
abs_vec_av | Input: Averaged absorption vector. |
sca_vec_av | Input: averaged scattering vector. |
lstep | Input: The length of the RTE step. |
rtp_planck_value | Input: Blackbody radiation. |

Optimize the zenith angle grid,
This method optimizes the zenith angle grid. For optimization it uses the interpolation method given by scat_za_interp (0 - linear interpolation, 1 - polynomial interpolation). As input it needs the intensity field calculated on a very fine zenith angle grid (za_grid_fine). The function picks out as many grid points as required to achieve the required accuracy (acc [%]). This methods optimizes only the intensity (first Stokes component) for 1D cases (first latitude and longitude of the intensity field. (Could be modified to optimize all Stokes components at the same time, if we don't want to use the clearsky field for grid optimuzation.)
