IDF Climate Change Tool

2018 – Western University

The IDFCC Tool is a publicly accessible, online tool that allows for local water managers and other interested stakeholders to apply Global Climate Model (GCM) outputs to local IDF curves to generate updated IDF curves that account for climate change impacts. The Tool provides access to outputs from 22 GCMs, and is pre-loaded with rain monitoring data from roughly 700 Environment Canada rain monitoring stations. This computerized web-based IDF tool integrates a user interface with a Geographic Information System (GIS). By creating or selecting a station (Gauged IDF) or selecting a location on the map (Ungauged IDF) the user will be able to carry out statistical analysis on historical data, as well as generate and verify possible future change based on a methodology using a combination of climate modeling outputs and locally observed weather data. Version 3 of the tool is now available and introduces a new dataset of IDF curves for ungauged locations in Canada. Users will be able to obtain IDF curves for any location in the country with the new module.
