Abstract
Tethys Platform is an open source framework for developing web-based applications for Earth Observation data. Our experience shows that Tethys significantly lowers the barrier for cloud-based app development, simplifies the process of accessing scalable distributed cloud computing resources and leverages additional software for data and computationally intensive modelling. The Tethys software development kit allows users to create web apps for visualizing, analyzing and modelling Earth Observation data. Tethys platform provides a collaborative environment for scientists to develop and deploy several Earth Observation web applications across multiple Tethys portals. We work in partnership with leading regional organizations world-wide to help developing countries use information provided by earth-observing satellites and geospatial technologies for managing climate risks and land use. This paper highlights the several Tethys portals and web applications that were developed as part of this effort. Implementation of the Tethys framework has significantly improved the Application Readiness Level metric for several NASA projects and the potential impact of Tethys to replicate and scale other applied science programs.

SERVIR is a joint initiative of the National Aeronautics and Space Administration (NASA) and the United States Agency for International Development (USAID) that seeks to build the capacity of local decision-makers dealing with a wide range of climate-related problems by making global earth observation data and associated tools available
Understanding and simulating the hydrologic cycle has been a scientific challenge for many decades, which is further complicated by the vast amount of data, computational horsepower, and human resources it requires (Sood and Smakhtin, 2015)
This paper presented and discussed a number of web applications developed by SERVIR Applied Science Team (AST) members primarily using the open source Tethys Platform software development toolkit for accessing, visualizing, analyzing spatial and temporal earth observation data and providing stakeholder decision support
Summary
SERVIR is a joint initiative of the National Aeronautics and Space Administration (NASA) and the United States Agency for International Development (USAID) that seeks to build the capacity of local decision-makers dealing with a wide range of climate-related problems by making global earth observation data and associated tools available. The SERVIR model brings together regional hubs supported by USAID grants with scientific experts in the areas of Agriculture and Food Security, Water Resources and Hydroclimatic Disasters, Land Cover and Land Use Change and Ecosystems, and Weather and Climate
