Columbia River Basin Extremes
d010014
Abstract:
This dataset provides 3-hourly hydrology and meteorological variables (runoff both on a 2D grid along a stream network vector, precipitation, and temperature) for about 4500 years over the Columbia river basin. It is being designed to use a large number of ensembles from the CMIP6 archive to sample unobserved decadal variability to improve our understanding of rare but extreme flood events. The CMIP models will be downscaled using the Intermediate Complexity Atmospheric Research model (ICAR) to a 5 km grid. These data will be bias corrected then used to run the SUMMA or VIC hydrology models to project variability in runoff, and routed with the mizuRoute streamflow model to project river flow volumes along the channel network.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
