ESTIMATION OF DAILY EVAPO-TRANSPIRATION (ET)FROM ONE TIME-OF-DAY REMOTELY SENSEDCANOPY TEMPERATURE
遥感瞬时作物表面温度估算农田全日蒸散总量

A simple model estimated daily total value of ET from one time of day measurement has been introduced in this paper.The model is made by two formulas, first is the aerodynamic resistance-energy balance model for estimating instantaneous values of E, second is a formula to assessment the daily total value of ET from one time of day measurements of net radiation, soil heat flux, air temperature, wind speed, crop canopy temperature, the data of latitute anl solar declination.
