The average surface resistance of a pine forest derived from Bowen ratio measurements

  • 132 Accesses

  • 69 Citations


Quartz crystal thermometers with ceramic tubes for the wet bulbs were used to measure vertical profiles of temperature and humidity above a pine forest. The effect of the supporting structures on the measurements and an objective method of calculating the Bowen ratio are described. The surface resistance was computed from the Bowen-ratio results. The diurnal variations in the average surface resistance of the forest for groups of dry days in Spring, Summer and Autumn are presented.
