Abstract

Hourly measurements of evaporation of intercepted rainfall were made for six months in a Sitka spruce forest in Central Wales (UK) with an eddy-correlation system. Sensible heat flux was measured with a three-dimensional sonic anemometer mounted on a mast above the forest, and evaporation was solved as the residual in the energy balance equation. Hourly evaporation was also estimated with the Penman-Monteith equation, using the eddy-correlation measurements to estimate the aerodynamic conductance. Wind direction dependent differences in surface roughness caused the aerodynamic conductance to vary from 0.09 to 0.29 m s
