This function checks for the given atmosphere dimension that I) the retrieval grids are defined II) and that they are covered by the corresponding atmospheric grid. If not the return is false and an output string is created to print the error to the user. If the grids are ok they are stored in an array and true is returned.

◆ get_perturbation_gridpos()

void get_perturbation_gridpos ( ArrayOfGridPos gp,
const Vector atm_grid,
const Vector jac_grid,
const bool &  is_pressure 
)

Calculate array of GridPos for perturbation interpolation.

This function constructs a perturbation grid which consists of the given retrieval grid with an extra endpoint added at each end. These endpoints lies outside the atmospheric grid. This enables the interpolation of an perturbation on the perturbation grid to be interpolated to the atmospheric grid. For this reason the function returns an ArrayOfGridPos.

If the atmospheric grid is a pressure grid, interpolation is made in logarithm of the atmospheric grid.

Parameters
gpArray of GridPos for interpolation.
atm_gridAtmospheric grid.
jac_gridRetrieval grid.
is_pressureTrue for pressure grid

◆ get_perturbation_limit()

void get_perturbation_limit ( ArrayOfIndex limit,
const Vector pert_grid,
const Vector atm_limit 
)

Get limits for perturbation of a box.

This is a helper function that calculates the limits where the perturbation should be added to the perturbation grid. This is needed for example by the particle perturbation that only should be applied for the cloudbox. The limits are defined as the outermost points lying within or just outside the box limits.

The atmospheric limits should be given in the same unit as the perturbation grid. And only the first and last element will be considered as limits.

Assertions are used to perform checks. The input grids are checked so that the atmospheric limits are containg within the perturbation grid. The limit indices are checked so that they are ordered in increasing order before return.

Parameters
limitThe limit indices in the perturbation grid
pert_gridThe perturbation grid
atm_limitThe atmospheric limits of the box.

◆ get_perturbation_range()

void get_perturbation_range ( Range range,
const Index index,
const Index length 
)

Get range for perturbation.

This is a helper function that calculates the range in which the perturbation should be added to the perturbation grid. This is needed to handle the edge effects. At the edges we want the perturbation to continue outwards.

Parameters
rangeThe range in the perturbation grid.
indexThe index of the perturbation in the retrieval grid.
lengthThe length of retrieval grid

◆ get_pointers_for_analytical_jacobians()

void get_pointers_for_analytical_jacobians ( ArrayOfIndex abs_species_i,
ArrayOfIndex is_t,
ArrayOfIndex wind_i,
const ArrayOfRetrievalQuantity jacobian_quantities,
const ArrayOfArrayOfSpeciesTag abs_species 
)

Help function for analytical jacobian calculations.

The function determines which terms in jacobian_quantities that are analytical absorption species and temperature jacobians.

abs_species_i* and is_t shall be sized to have the same length as jacobian_quantities. For analytical absorption species jacobians, abs_species_i is set to the matching index in abs_species*. Otherwise, to -1. For analytical temperature jacobians, is_t is set to 1. Otherwise to 0.

Parameters
abs_species_iOut: Matching index in abs_species
is_tOut: Flag for: Is a temperature jacobian?
jacobian_quantitiesAs the WSV.
abs_speciesAs the WSV.
