calc.dist.dir: Internal function used to compute the inter-site directional...

In ProbForecastGOP: Probabilistic weather forecast using the GOP method

Description

Calculates the directional distance between sites of a random variable. This is an internal function called by the avg.variog.dir and the EmpDir.variog function when computing the directional empirical variogram.

Usage

calc.dist.dir(coord1,coord2,id,tol.angle.rad1,tol.angle.rad2,type)

Arguments

coord1	numeric vector containing the longitudes of the meteorological stations.
coord2	vector containing the latitudes of the metereological stations.
id	vector with the id of the metereological stations.
tol.angle1	number giving a lower bound for the tolerance angle (measured in radians).
tol.angle2	number giving an upper bound for the tolerance angle (measured in radians).
type	character string indicating the direction to use for variogram computations. Possible values are either 'E' (for East-West) or 'N' (for North-South).

Details

This function is an internal function that is used and called by the avg.variog.dir functions when estimating the directional empirical variogram of a random variable observed at different meteorological stations.

- Defaults -

None.

Value

The function returns a square matrix of dimension n by n, where n is the length of the vector coord1 where the (i,j) entry of represents the directional distance between the i-th and the j-th metereological stations.
