Hellmann function to extrapolate wind speed from 10 and 50 meters to higher altitudes

Description

Hellmann function to extrapolate wind speed from 10 and 50 meters to higher altitudes

Usage

fHellmann(W10M, W50M, na = 0, inf = 0, lo = 0, up = 0.6, ...)

fH(W10M, W50M, na = 0, inf = 0, lo = 0, up = 0.6, ...)

Arguments

W10M	wind speed (m/s) at 10 meters altitude
W50M	wind speed (m/s) at 50 meters altitude
na	values to return in the case of NA
inf	values to return instead of infinite
lo	lower limit, zero by default to control negative values
up	lower limit, 0.6 by default to control excessive values

Value

a numeric vector with estimated Hellmann exponent.
