CAMELS Dataset

BY DOWNLOADING THE DATASET, YOU ARE AGREEING TO BE BOUND BY OUR TERMS OF USE. IF YOU DO NOT AGREE TO THESE TERMS, YOU ARE NOT AUTHORIZED TO DOWNLOAD THIS DATASET.

The CAMELS data set consists of two data sets: the hydrometeorological time series introduced in Newman et al. (2015) and the catchment attributes introduced in Addor et al. (2017). These two data sets are available for download separately.

Thank you and please contact Lara Ziady, ziady@ucar.edu, if you encounter difficulty in transferring the files.

 


CAMELS hydrometeorological time series

Download link to the CAMELS hydrometeorological time series described in Newman et al. (2015):

 

 

 

 

 

 

To retrieve the entire timeseries dataset, all five files should be downloaded.  The first file containts all the basin forcing data for all three meteorology products, observed streamflow, basin metadata, readme files, and basin shapefiles.  The next three files contain all the model output for the various forcing datasets denoted in the link names.  Finally, the full resolution basin shapefile contains the original basin boundaries from the geospatial fabric.

Note there are two versions of the basin shapefiles included in this dataset.  The shapefile included with the basin forcing data was used to compute the basin forcing data and is a simplified representation of the basin boundariesr which will include small holes in the interior of some basins where sub-basin HRU simplifications do not match.  The full resolution shapefile does not have those discontinuties.  The user can best determine which shapefile (or both) is appropriate for their needs.
