convert_windSpeed_to_2m {simET}

Convert wind speed to the standard of 2m

Description

For the calculation of evapotranspiration, wind. Speed measured at 2 m above the surface is required. To adjust wind speed data obtained from instruments placed at elevations other than the standard height of 2 m, a logarithmic wind speed profile may be used for measurements above a short grassed surface.

Usage

convert_windSpeed_to_2m(uz, z)

Arguments

uz

measured wind speed at z m above ground surface [m s-1].

z

height of measurement above ground surface [m].

Value

A vector for wind speed at 2 m above ground surface [m s-1].
