EDDY CORRELATION MEASUREMENTS OF CONVECTIVEHEAT FLUX AND ESTI:MATION OF EVAPORATIVE HEAT FLUX OVER GROWING TEA

Abstract

The EAAFRO catchment experiments (Pereira et al., 1962) were designed and executed to investigate the water use of different Vegetative covers, including tea estates, over periods of the order of a year. The eddy correlation experiment reported here, by providing Estimates of daily evaporation over several days, offers an independent check on the catchment results; another method of water use estimation, through a monitoring of soil moisture changes, is described in Section 2.2.3. Much valuable information would be available if the changes of water use from day to day and within a day could be measured and understood. This eddy correlation experiment was therefore designed to yield additional data on the pattern of evapo transpiration from tea within a day.
