void grid2grid_index ( Matrix &  is,
const Vector &  x0,
const Vector &  xp 
)

Gives indecies for conversion between vertical grids.

This function gives the indeces of the grid points affected by a change at a set of retrieval points. That is, a first step to calculate dkappa/dkp (see Equation 4 of the AUG section on "Basic atmospheric WFs). The second step is performed by the function GRID2GRID_WEIGHTS found below.

This function can be used to convert LOS WFs to WFs for vertical altitudes.

The profile/function for the retrieved quantity is treated to be piecewise linear. With other words, the base functions are tenth functions. The functions areis treated to be 0 outside the end points.

The function returns a 2 column matrix, where column 1 is the lowest index affected and column 2 the highest index. If no points are affected -1 are returned.

An example:

x0 = [1 2 3 4 5 6 7] and

xp = [0 1 2 3 4.5 5 5.5 6 8] gives

Is = [-1 -1 0 0 1 1 2 3 3 3 4 4 -1 -1 5 6 6 6 ]

Note that the XP point 5.5 gives -1 as this point not embraces any point of X0 as there are retrieval points at the neighbouring X0 points.

X0 is the original grid. For example, the LOS grid. XP is the retrieval grid. For example, vertical altitudes.

Both vectors most be sorted with increasing values. The length of XP must be > 1.

The algorithm used here is not the most effective. However, more elaborated algorithms were tested but they failed for some special case, and instead a simplistic approach was used.

Return values:
is two column matrix with indecies of x0
Parameters:
x0 grid for some variable
xp retrieval grid

void grid2grid_weights ( Vector &  w,
const Vector &  x0,
const Index &  i1,
const Index &  i2,
const Vector &  xp,
const Index &  ip 
)

Gives weights for conversion between vertical grids.

This function returns the derivative dkappa/dkp (see the AUG section on "Atmospheric WFs"), here dennoted as the weight, for the indeces selected.

This is an accompanying function to GRID2GRID_INDEX. This latter function gives the indeces for which the weight > 0.

The weight is

w = abs( (x0-xp(ip+-1)) / (xp(ip)-xp(ip+-1)))

where x0 is the point of the original grid (kappa), xp(ip) is the considered retrieval point and xp(ip+-1) is the retrieval point on the other side of x0.

Return values:
w weights for each point in x0
Parameters:
x0 the original grid, e.g. the LOS grid.
i1 first index of x0 to consider
i2 last index of x0 to consider
xp retrieval grid, e.g. vertical altitudes
ip index of retrieval point

void grid2grid_weights_total ( ArrayOfMatrix &  W,
const Los &  los,
const Vector &  k_grid 
)

Gives weights for conversion between vertical grids.

This function returns the derivative dkappa/dk (see the AUG section on "Atmospheric WFs"), here dennoted as the weight, for the grid specified by k_grid.

This uses GRID2GRID_WEIGHTS function which calculate the weights for a single grid point

Return values:
W weights for each point in x0
Parameters:
Los structure for the line of sight
k_grid the grid to calculate the weights
