WORKSPACE METHOD: CloudboxGetIncoming.

Calculates incoming radiation field of the cloudbox by repeated radiative transfer calculations.

The method performs monochromatic pencil beam calculations for all grid positions on the cloudbox boundary, and all directions given by scattering angle grids (scat_za/aa_grid). Found radiances are stored in scat_i_p/lat/lon which can be used as boundary conditions when scattering inside the cloud box is solved by the DOIT method.

Can only handle iy_unit=1 (intensity in terms of radiances). Other output units need to be derived by unit conversion later on (e.g. after yCalc).

WORKSPACE METHOD: CloudboxGetIncoming1DAtm.

As CloudboxGetIncoming but assumes clear sky part to be 1D. The incoming field is calculated only for one position and azimuth angle for each cloud box boundary, and obtained values are used for all other postions and azimuth angles. This works if a 3D cloud box is put into an 1D background atmosphere.

This method can only be used for 3D cases.

WORKSPACE METHOD: doit_i_fieldIterate.

Iterative solution of the VRTE (DOIT method).

A solution for the RTE with scattering is found using the DOIT method: 1. Calculate scattering integral using doit_scat_field_agenda. 2. Calculate RT with fixed scattered field using doit_rte_agenda. 3. Convergence test using doit_conv_test_agenda.

Note: The atmospheric dimensionality atmosphere_dim can be either 1 or 3. To these dimensions the method adapts automatically. 2D scattering calculations are not supported.

WORKSPACE METHOD: doit_i_fieldSetClearsky.

Interpolate clearsky field on all gridpoints in cloudbox.

This method uses a linear 1D/3D interpolation scheme to obtain the radiation field on all grid points inside the cloud box from the clear sky field on the cloud box boundary. This radiation field is taken as the first guess radiation field in the DOIT module.

Set the all_frequencies to 1 if the clearsky field shall be used as initial field for all frequencies. Set it to 0 if the clear sky field shall be used only for the first frequency in f_grid. For later frequencies, doit_i_field of the previous frequency is then used.

WORKSPACE METHOD: doit_i_fieldSetFromdoit_i_field1D_spectrum.

Sets the initial cloudbox intensity field from doit_i_field1D_spectrum.

This method sets the (monochromatic) first guess radiation field inside the cloudbox from a precalculated doit_i_field1D_spectrum, e.g., from the solution of a similar atmospheric scenario. The dimensions of doit_i_field1D_Spectrum have to be consistent with the DOIT setup in terms of frequencies, pressure levels inside the cloudbox, polar angles used as well as the stokes dimension. Incoming field on the cloudbox boundaries is adapted to the actual clearsky incoming field as, e.g., calculated by DoitGetIncoming.

WORKSPACE METHOD: doit_i_fieldUpdate1D.

RT calculation in cloudbox with fixed scattering integral (1D).

Updates the radiation field (DOIT method). The method loops through the cloudbox to update the radiation field for all positions and directions in the 1D cloudbox.

Note: This method is very inefficient, because the number of iterations scales with the number of cloudbox pressure levels. It is recommended to use doit_i_fieldUpdateSeq1D.

WORKSPACE METHOD: doit_scat_fieldCalcLimb.

Calculates the scattering integral field in the DOIT module (limb).

The scattering integral field is the field generated by integrating the product of phase matrix and the Stokes vector over all incident angles.

For limb simulations it makes sense to use different zenith angle grids for the scattering integral part and the RT part, because the latter part requires a much finer resolution near 90 degrees. Taking an optimized grid for the RT part and an equidistant grid for the scattering integral part saves very much CPU time. This method uses the equidistant za_grid defined in DoitAngularGridsSet* and it should always be used for limb simulations.

For more information please refer to AUG.

	)

WORKSPACE METHOD: doit_za_grid_optCalc.

Zenith angle grid optimization for scattering calculation.

This method optimizes the zenith angle grid. As input it requires a radiation field (doit_i_field) which is calculated on a very fine zenith angle grid (scat_za_grid). Based on this field zenith angle grid points are selected, such that the maximum difference between the radiation field represented on the very fine zenith angle grid and the radiation field represented on the optimized grid (doit_za_grid_opt) is less than the accuracy (acc). Between the grid points the radiation field is interpolated linearly or polynomially depending on doit_za_interp.

Note: The method works only for a 1D atmosphere and for one frequency.

		const Verbosity &	verbosity
	)

WORKSPACE METHOD: DoitAngularGridsSet.

Sets the angular grids for DOIT calculation. In this method the angular grids for a DOIT calculation are specified. For down-looking geometries it is sufficient to define N_za_grid* and N_aa_grid. From these numbers equally spaced grids are created and stored in the WSVs scat_za_grid and scat_aa_grid*.

For limb simulations it is important to use an optimized zenith angle grid with a very fine resolution about 90 degrees. Such a grid can be generated using doit_za_grid_optCalc. The filename of an optimized zenith angle grid can be given as a keyword (za_grid_opt_file).

If a filename is given, the equidistant grid is used for the calculation of the scattering integrals and the optimized grid is applied for integration of the radiative transfer equation.

For down-looking cases no filename should be specified (za_grid_opt_file = "" ) Using only the equidistant grid makes sense to speed up the calculation.

Writes DOIT iteration fields.

This method writes intermediate iteration fields to xml-files. The method can be used as a part of doit_conv_test_agenda.

The iterations to be stored are specified by iterations, e.g.: iterations = [3, 6, 9] In this case the 3rd, 6th and 9th iterations are stored in the files 'doit_iteration_3.xml', 'doit_iteration_6.xml' ... If a number is larger than the total number of iterations, this number is ignored. If all iterations should be stored set iterations = [0]

WORKSPACE METHOD: iyInterpCloudboxField.

Interpolates the intensity field of the cloud box.

This is the standard method to put in iy_cloudbox_agenda if the the scattering inside the cloud box is handled by the DOIT method.

The intensity field is interpolated to the position (specified by rtp_pos*) and direction (specified by rtp_los) given. A linear interpolation is used for all dimensions.

The intensity field on the cloux box boundaries is provided by scat_i_p/lat/lon* and these variables are interpolated if the given position is at any boundary.

Interpolation of the internal field is not yet possible.

WORKSPACE METHOD: iyInterpPolyCloudboxField.

As iyInterpCloudboxField but performs cubic interpolation.

Works so far only for 1D cases, and accordingly a cubic interpolation along scat_za_grid is performed.
