Interpretive Summary: The use of automated weather stations has dramatically increased in the United States and around the world. In many regions and/or states, these stations are assembled into weather networks. The networks serve many purposes, but the estimation of water use data [evapotranspiration (ET) from crops and/or landscapes] is an important application. This paper reviews the various approaches for collecting, transmitting, and quality assuring the weather data. It also summarizes how several major networks calculate, package, and disseminate ET information. This information can lead to significant improvements in water management.

Technical Abstract: In the United States, automated weather networks have grown rapidly in number and extent. One important application of real-time weather data is the estimation of evapotranspiration (ET) from crops and/or landscapes. Networks use various approaches for collecting, transmitting, and quality assuring the "raw" weather data, and for calculating, packaging, and disseminating ET information. When incorporated into an irrigation scheduling program, this information can lead to significant improvements in water management.
