longwave.conductance

Longwave Radiative Transfer Conductance of the Canopy

Calculation of physical (e.g. aerodynamic conductance, surface temperature),
and physiological (e.g. canopy conductance, water-use efficiency) ecosystem properties
from eddy covariance data and accompanying meteorological measurements. Calculations
assume the land surface to behave like a 'big-leaf' and return bulk ecosystem/canopy variables.
