【實用工具app】Bushland Ref. ET Calculator|最夯免費app-綠色工廠好玩App

Bushland Reference ET Calculator was developed at the USDA-ARS Conservation and Production Research Laboratory, Bushland, Texas. Although it was designed and developed for use mainly by producers and crop consultants to manage irrigation scheduling, it can also be used in educational training, research, and other practical applications. It uses the ASCE Standardized Reference Evapotranspiration (ET) Equation for calculating grass and alfalfa reference ET at hourly and daily time steps. This program uses the more complex equation for estimating clear-sky solar radiation provided in the Appendix D of the ASCE-EWRI ET Manual. Users have the option of using a single set or time series weather data to calculate reference ET. Daily reference ET can be calculated either by summing up the hourly ET values for a given day or by using daily averages of the climatic data.
