Computerized Tool for the Development of Intensity-Duration-Frequency Curves under Climate Change – Version 4.0
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.
We also encourage you to check out the user manual and technical documentation available in the Help section.
