Increased model complexity and data quantities have raised the computing power requirement for efficient evapotranspiration (ET) estimation. A cloud-based service is presented to encapsulate and publish the ETWatch modeling algorithms as web application programming interfaces (APIs) in a consistent style to provide extensible model calculation service and data storage service in a cloud platform for water managers and stakeholders. The prototype system, named ETWatch Cloud allows users to rapidly and easily set up an ET generation project for any region of interest by invoking APIs directly to produce ET data using a web browser or local integrated development environment. The case study demonstrates that ETWatch Cloud can provide a highly scalable and interoperable ET generation tool for stakeholders from ET community, helping to facilitate the application of remote sensing-based ET algorithms for water management in hydrology sector.

模型复杂性和数据量的增加提高了对高效蒸散 (ET) 估算的计算能力要求。提出了一种基于云的服务，以一致的风格将 ETWatch 建模算法封装和发布为 Web 应用程序编程接口 (API)，以便在云平台中为水管理人员和利益相关者提供可扩展的模型计算服务和数据存储服务。名为ETWatch Cloud的原型系统允许用户通过使用Web浏览器或本地集成开发环境直接调用API来生成ET数据，从而快速轻松地为任何感兴趣的区域设置ET生成项目。案例研究表明，ETWatch Cloud 可以为来自 ET 社区的利益相关者提供高度可扩展和可互操作的 ET 生成工具，
