WebThis volume’s authors make a case for phenology—not so much for phenology as it is commonly understood (a field technique of agricultural meteorology), but as an aspect of analysis and management of ecological systems or ecosystems. We have indicated its importance earlier (e.g., Lieth, 1970, 1971; Lieth and Radford, 1971) but our experience … Webaridity assessments, or irrigation planning etc. (FAO 1996, Lieth 1975), it is crucial to find the most appropriate method to estimate ET 0. Differences among methods often reach hundreds of millimetres per growing season (Federer et al. 1996), and accuracy of a given method depends heavily on the climatic conditions of the study site.
