Detailed Description

Simple structure function based on distance, elevation, and land area fraction.

Constructor & Destructor Documentation

gridpp::BarnesStructure::BarnesStructure	(	float	h,
		float	v = `0`,
		float	w = `0`,
		float	hmax = `MV`
	)

Exponential structure function.

Barnes.

Parameters

h	Horizontal decorrelation length >=0 [m]
v	Vertical decorrelation length >=0 [m]. If 0, disable decorrelation.
w	Land/sea decorrelation length >=0 [1]. If 0, disable decorrelation.
hmax	Truncate horizontal correlation beyond this length [m]. If undefined, 3.64 * h.

gridpp::BarnesStructure::BarnesStructure	(	Grid	grid,
		vec2	h,
		vec2	v,
		vec2	w,
		float	min_rho = `StructureFunction::default_min_rho`
	)

Barnes structure function where decorrelation varyies spatially.

Parameters

grid	Grid of decorrelation field
h	Horizontal decorrelation length field >=0, same size as grid [m]
v	Vertical decorrelation length field >=0 [m]. Set all to 0 to disable decorrelation.
w	Land/sea decorrelation length field >=0 [1]. Set all to 0 to disable decorrelation.
min_rho	Truncate horizontal correlation when rho less than this value [m].
