About this Service

The World Weather for Water Data Service (W3S) is a Data as a Service (DaaS) platform that enables users to download various climate data products, such as precipitation, maximum temperature, and minimum temperature, from popular sources. Users can define their region of interest within any watershed globally. The weather data is available in multiple formats compatible with hydrologic models like SWAT, as well as in generic CSV format for other models. Essentially, W3S serves as a global weather data hub, designed to help users quickly develop both conceptual and data-driven rainfall-runoff and hydro-ecological models.

Code

The frontend of the application is developed using R Shiny. The backend incorporates the Timeloop python package to schedule and manage jobs. Build automation is streamlined through a straightforward pipeline: a Forgejo action handles image builds, followed by a Watchtower component that monitors the image registry. Comprehensive backend testing is conducted with Pytest, covering both integration and unit tests to ensure functionality.
