| Reference evapotranspiration, ETo, is important as it is used to determine the evaporative demand of the atmosphere. there is a need for continued studies to determine the reference evepotranspiration of different locations as well as its relationship with various climatic parameters for the prediction of water demands for human and ecological reasons. A study undertaken to determine the relationship between ETo, obtained using the Food and Agriculture Organization of United Nations, Penman-Monteith (FAO-56 PM) method, and some climatic data in Umudike, Nigerian environment are presented. The climatic parameters considered are solar radiation, sunshine hours and wind speed. The interactions of climatic parameters in the input variables of the ETo model,... |
