Abstract:
The Penman potential evapotranspiration model has been expanded and generalized for a vide range of climatic conditions by J. Doorenbos and W. 0. Pruitt (1975, FAO Irrig. & Drain. Pap. 24). Their comprehensive model relies heavily on tabulations and graphs to facilitate its application in remote areas where computer facilities are lacking. Future applications of this model have been substantially enhanced by our development of a program that runs on a HP-41C /CV calculator. The RPN program occupies 1778 bytes of memory, and will run on a 41CV, or a 41C with a quad memory module. A printer is also needed. The required climatic data can be input in a variety of forms, and program execution was planned with particular attention to the non- technical user. The entire calculator system (41CV, printer, card reader) cost less than $750, and provides for very portable use with a high degree of computing power.
