Intensity Duration Frequency Curves for New York State: Future Projections for a Changing Climate

Description

Numerous studies have documented significant increases in both the frequency and magnitude of extreme precipitation in the northeastern U.S. since the mid- to late-20th century, and it will likely continue to increase throughout the 21st century. In consideration of these impacts, the Northeast Regional Climate Center partnered with the New York State Energy Research and Development Authority to downscale global climate model output and create extreme precipitation projections that will ultimately be incorporated into climate change adaptation planning for New York State.

This webpage showcases final research products and displays historical and projected precipitation data from 157 weather stations in and around the state of New York, including:

  1. Historical and future downscaled intensity-duration-frequency (IDF) curves for each station;
  2. Gridded maps illustrating projected changes in return period precipitation amounts; and
  3. Gridded maps illustrating projected changes in the recurrence intervals of historical precipitation thresholds.
