About this Service
This application, also called the World Weather for Water Data Service (W3S), is a Data as a Service (DaaS) platform that allows
application users to download climate (precipitation, maximum temperature & minimum temperature) data of a pre-specified region
within any watershed across the globe. The weather data can be downloaded in multiple hydrologic model
compatible formats like SWAT and generic CSV format for other hydrologic models.
W3S can thus be considered a global weather data playground designed to swiftly assist users with developing
both conceptual and data-driven rainfall-runoff and hydro-ecological models.
Precipitation Data: Daily timestep; 1999 onwards. Original data source: IMERG: Integrated Multi-satellite Retrievals for GPM,
Final Run product, V06.
Temperature Data: Daily timestep: 1999 onwards. Original data source: Climate Prediction Center of Physical Sciences Laboratory,
