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.

Data Sources

Historical Data:
Precipitation Data: Daily timestep; 1999 onwards. Original data source: IMERG: Integrated Multi-satellite Retrievals for GPM, (https://gpm.nasa.gov/data/imerg). Final Run product, V06.
Temperature Data: Daily timestep: 1999 onwards. Original data source: Climate Prediction Center of Physical Sciences Laboratory, (https://psl.noaa.gov/data/gridded/data.cpc.globaltemp.html)

Weather Data Request

In order to download historical weather data, first choose a geographical area by either i) Using the polygon drawing tool (left side of map) to draw a custom area or ii) uploading a zipped boundary (single polygon) shape file, using the 'DATA SELECTOR' panel. Data may be filtered further by selecting climate parameter and date ranges in the 'DATA SELECTOR' before submission of request. Once a valid data requet is selected, users will be required to provide and email address for further processing of their data request. Please note that there may be a wait time of a few hours or days before data is processed and is available for download.

Shape File Format

If preferred area selection mechanism is a user-provided Shape File then please make sure that all files associated with the uploaded shape input (e.g., *.shp, *.dbf etc) are in a zipped folder. Also the shape should be a boundary / single polygon.

Track Data Request

Users will be intimated via email once a data request is processed. They can then download the requested data from the Track Requests tab. Users will be required to provide their email address to be able to download the requested data. Users can also track progress of all pending data requests from the Track Requests tab.
