Comparison of Evapotranspirations Measured by Lysimeter and Calculated by Various Estimating Methods

摘要: The accuracy of methods for estimating evapotranspiration at upland in a humid area was investigated soybean field. First, hourly were estimated using the Bowen ratio method, Brown‐Rosenberg Batholic method and Monteith method. Second, daily Ostromeki Makkink Stephens Turc Jensen van Bavel Bavel‐Businger Penman Correlativity between observed values compared, superiority these discussed. When meteorological data available, accurate next to And when showed high though this only use average temperature solar radiation.
