Spatial Variability And Error Limits Of Reference Evapotranspiration Estimates, Thomas W. Ley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The overall objective of this research was to develop a methodology for assessing the spatial variability and error limits of reference evapotranspiration (ETr) estimates from a weather station network. Likely errors introduced into ETr estimates due to sensor measurement variability and nonstandard site conditions were investigated. Temporal and spatial correlation structures of the weather variables used to compute ETr and of ETr data collected over a three-year period by an operational agricultural weather station network were studied.
Results indicated that ETr errors are minimal compared to inherent model error when sensors (of the type …
