The fading imprint of aridity along river networks — dataset (v1.0.0)

Dataset supporting the manuscript: The fading imprint of aridity along river networks The files provide inputs and outputs for the Mississippi River Basin (MRB) ecohydrologic analysis, including the spatial stream-network (SSN) objects, watershed polygons (HydroBASINS), and posterior draws/summaries from a Bayesian isotope mass-balance model (“mrBayes” at https://github.com/SPATIAL-Lab/mrBayes). Use version DOIs for exact reproduction. How to obtainAll files are available at doi:10.5281/zenodo.17545916 (this record). File inventory mrb.rivFcopy.zip — Spatial data products used to build the spatial stream network (References in manuscript). mrbevap.ssn.zip — Final MRB landscape stream-network (SSN) for the spatial model. posterior_matrix.rds — Posterior matrix of MCMC samples from the MRB isotope mass-balance model. dstreams_bay_extended.RDS — Stream-network with Bayesian component summary statistics. dstreams_bay.RDS — SSN-ready reach-level dataset for d-excess (primary analysis table). GP_raw.RDS — Great Plains polygon (EPA’s SDAM GP). lowmrb.RDS, midmrb.RDS, midlowmrb.RDS, uppermrbbas.RDS, ohiobas.RDS, mergedMRBpoly.RDS — HydroBASINS watershed polygons (Lower, Middle, Middle–Lower, Upper MRB; Ohio River Basin; merged MRB polygon).
