◆ check_retrieval_grids()

bool check_retrieval_grids	(	ArrayOfVector &	grids,
		ostringstream &	os,
		const Vector &	p_grid,
		const Vector &	lat_grid,
		const Vector &	lon_grid,
		const Vector &	p_retr,

		const String &	lat_retr_name,
		const String &	lon_retr_name,
		const Index &	dim
	)

Check that the retrieval grids are defined for each atmosphere dim.

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.

Parameters

grids	The array of retrieval grids.
os	The output string stream.
p_grid	The atmospheric pressure grid
lat_grid	The atmospheric latitude grid
lon_grid	The atmospheric longitude grid
p_retr	The pressure retrieval grid.
lat_retr	The latitude retrieval grid.
lon_retr	The longitude retrieval grid.
p_retr_name	The control file name used for the pressure retrieval grid.
lat_retr_name	The control file name for the latitude retrieval grid.
lon_retr_name	The control file name for the longitude retrieval grid.
dim	The atmosphere dimension

Returns: Boolean for check.

◆ 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

gp	Array of GridPos for interpolation.
atm_grid	Atmospheric grid.
jac_grid	Retrieval grid.
is_pressure	True 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

limit	The limit indices in the perturbation grid
pert_grid	The perturbation grid
atm_limit	The 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

range	The range in the perturbation grid.
index	The index of the perturbation in the retrieval grid.
length	The length of retrieval grid
