Summary
This data release documents the data used for the associated publication "Evaluating hydrologic region assignment techniques for ungaged watersheds in Alaska, USA" (Barnhart and others, 2022) The data sets within this release are stored in 14 files: (1) Streamflow observations and sites used. (2) Statistically estimated streamflow values computed for each site. (3) Streamflow statistics computed from observed and estimated streamflow values at each site, basin characteristics for each site, and hydrologic regions (clusters) for each site. (4) A dataset describing the optimal number of hydrologic regions into which the considered sites were grouped. (5) P-values from a multiple comparisons analysis testing for statistical differences [...]

(4) A dataset describing the optimal number of hydrologic regions into which the considered sites were grouped. (5) P-values from a multiple comparisons analysis testing for statistical differences between clusters for each basin characteristic and streamflow statistic. (6) A matrix of zeros and ones describing the performance of each hydrologic region assignment technique considered in the publication associated with this release. (7) A dataset of variable importance generated by random forest modeling-based hydrologic region assignment techniques evaluated. (8-14) Daily datasets of simulated SnowModel (Liston and Elder, 2006) runoff (snowmelt + rainfall), precipitation, glacial melt, snow water equivalent, snow covered area, liquid precipitation, and air temperature for Alaska, USA at a 1 km grid cell size.

Barnhart, T. B., Farmer, W. H., Hammond, J. C., Sexstone, G. A., Curran, J. H., Koch, J. C., & Driscoll, J. M. (2022). Evaluating hydrologic region assignment techniques for ungaged basins in Alaska, USA. River Research and Applications, 1– 16. https://doi.org/10.1002/rra.4028
This data release supports Barnhart and others (2022) in documenting and archiving the datasets used for that publication. This work furthers our understanding of how to assign ungaged watersheds to hydrologic regions (clusters) for hydrologic modeling and other uses.
