biostudies-literatureUnknown42Wilkins ACSIROACARPChloride deposition-rate measurements at points within Australia are upscaled to the entire continent on a regular 0.05° grid. The upscaling uses a double-exponential correlation between deposition rate and distance to the coast, where the parameters in the double-exponential are spatially varying. These parameters are estimated using least-squares with Tikhonov regularisation to ensure minimal spatial variability. A calibration-constrained, null-space Monte-Carlo analysis is used to quantify uncertainty in the prediction. The resulting dataset consists of the best-fit chloride deposition rates across Australia, as well as estimates of uncertainty. The dataset can be used for various purposes including: estimating groundwater recharge through the use of the chloride mass-balance method; catchment salt balance estimates; regional investigations of groundwater hydrochemistry; and, corrosion prediction.Data in brief108189https://www.ebi.ac.uk/biostudies/studies/S-EPMC9065633biostudies-literatureAustralian gridded chloride deposition-rate dataset.PMC9065633Davies PLouth-Robins TDawes WGao LCrosbie RRaiber MWilkins AfalseAustralian gridded chloride deposition-rate dataset.Chloride deposition-rate measurements at points within Australia are upscaled to the entire continent on a regular 0.05° grid.
