Abstract : Some problems involved in the computation of saturation vapor pressure of water for meteorological applications are discussed. Two formulations for saturation vapor pressure in the pure phase over a plane surface of water or ice are considered; namely, the Gpff-Gratch formulation, which is the internationally accepted standard, and the Tetens formulation, which is widely used because of its simplicity. It is concluded that the Tetens formulation gives results sufficiently close to those of the Goff-Gratch formulation for most meteorological applications. (Author)
