soil is not limited. Actual evapotranspiration: Water loss from a plant/soil combination under existing meteorological, soil and biological conditions.
23 2.7 Atmospheric Pressure 2.7.1 General comments Atmospheric pressure is regularly measured at stations of the international meteorological network for synoptical and weather forecast purposes. In agricultural meteorology, this parameter has no direct importance and it is therefore, not included in the standard observation programme. However, atmospheric pressure data is required for such computations as air humidity and evaporation. Generally, mean pressure values as given by the altitude/pressure relationship is sufficient, or otherwise data from nearby synoptic stations can be used. Share with your friends: |
