Non-stationary NG-IDF Dataset from ICAR-DHSVM for Yakima River Basin (WA): CanESM5

This dataset contains the NG-IDF (Next-Generation Intensity-Duration-Frequency) data generated using ICAR-DHSVM simulations for all grid cells over the Yakima River Basin in Washington State (file: CanESM5_gridcell.zip). It also includes aggregated data for the Yakima Training Center (YTC) area (file: CanESM5_YTC.zip).

The ICAR model was used to downscale data from five CMIP6 GCMs for historical periods and three future scenarios (SSP2-4.5, SSP3-7.0, and SSP5-8.5). Due to data limitations, the datasets for the five GCMs are hosted under different DOIs. This site specifically provides data for the CanESM5 GCM. The datasets for other GCMs can be accessed at the following locations:

CMCC-CM2-SR5: 10.5281/zenodo.14553836

MIROC-ES2L: 10.5281/zenodo.14553866

MPI-ESM1-2-LR: 10.5281/zenodo.14556337

NorESM2-MM: 10.5281/zenodo.14556351

Each GCM dataset includes historical data and projections for the three future scenarios. For each scenario, data are provided for nine land-use/land-cover (LULC) types consistent with the NLCD classification: Crop, Deciduous Forest, Evergreen Forest, Grass, Mixed Forest, Open, Pasture, Shrub, and Wetland.

Within each folder, the following are included:

3-hour time series data

Annual maximum W data

NG-IDF curves
