Calculation of the Monin-Obhukov-Length. The calculation depends on the stability of the atmosphere. This value will be taken from the Gradient-Richardson-Number. The profile and stability parameterization uses Bendix/Foken method background.

Usage

turb_flux_monin(...)

# Default S3 method
turb_flux_monin(
  z1 = 2,
  z2 = 10,
  v1,
  v2,
  t1,
  t2,
  elev,
  surface_type = NULL,
  obs_height = NULL,
  ...
)

# S3 method for class 'weather_station'
turb_flux_monin(weather_station, ...)

Arguments

...

Additional arguments.

z1

v1

Windspeed at lower height (e.g. height of anemometer) in m/s.

v2

Windspeed at upper height in m/s.

t1

Temperature at lower height (e.g. height of anemometer) in °C.

t2

Temperature at upper height in °C.

elev
