calc_footprint_hsieh: Two-dimensional footprint calculation

In grahamstewart12/footprints: What the Package Does (One Line, Title Case)

Description

Two-dimensional footprint calculation

Usage

calc_footprint_hsieh(grid, wd, ustar, mo_length, v_sigma, zm, zd, zo, ...)

Arguments

grid	A list of matrices as returned by grid_init().
wd	A numeric vector, wind direction in degrees from North.
ustar	A numeric vector, friction velocity in m+1s-1.
mo_length	A numeric vector, Monin-Obukhov length in m.
v_sigma	A numeric vector, standard deviation of the crosswind component.
zm	A numeric vector, measurement height in m,
zd	A numeric vector, zero-plane displacement height in m.
zo	A numeric vector, aerodynamic roughness length in m.
...	To be left empty, for flexible calls to a footprint function.

Value

A matrix with same dimensions as each item of grid.
