About

OpenET uses best available science to provide easily accessible satellite-based estimates of evapotranspiration (ET) for improved water management across the western United States.

Sustainable water management is one of the most challenging issues of our time, especially in the arid western U.S. Adequate water supplies are crucial to maintaining the health of communities, rivers, and wildlife, and nothing is more important to agriculture’s ability to produce food for the world’s growing population. Maximizing the benefits of our water supplies requires careful measurement of their availability and use. For irrigated agriculture, satellite-based estimates of evapotranspiration (ET) provide a measure of the water used to grow food — the biggest share of water consumption in most arid environments around the world. However, access to ET data has been limited and expensive, keeping it out of the hands of most water users and decision-makers.

OpenET provides open, easily accessible satellite-based ET data for improved water management. The OpenET collaborative includes leading national and international experts in remote sensing of ET, cloud computing, and water policy, partnered with nationally recognized web development teams and leaders in the western agriculture and water management communities.

The OpenET Team

 

The OpenET Team includes leading national and international experts in remote sensing of ET, cloud computing, water policy, and water markets, partnered with nationally recognized web development teams and leaders in the western agriculture and water management communities.

OpenET is very grateful to the support it has received from the S. D. Bechtel, Jr. Foundation; Gordon and Betty Moore Foundation; The Walton Family Foundation; Windward Fund; The Keith Campbell Foundation for the Environment; Lyda Hill Philanthropies; The Laney and Pasha Thornton Foundation; the Water Funder Initiative; Desert Research Institute Maki Endowment; the North, Central, and South Delta Water Agencies; the NASA Western Water Applications Office and the NASA Applied Sciences Program. In-kind support is provided by partners in the agricultural and water management communities, Google Earth Engine, and the Water Funder Initiative.
