Australian 0.05º gridded chloride deposition v2

Abstract

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on the known details at the time of acquisition.

Grid surfaces at a resolution of 0.05° x 0.05° showing the chloride deposition rate (kg/ha/year) across Australia based upon distance from the coast. The dataset and the derivative 95% confidence interval for upper and lower datasets is made available as ArcInfo ASCII Grid format.

This revised version includes the uncertainty in the chloride deposition rate surface quantified using the mean, standard deviation and skewness (grids included).

Purpose

Has a number of applications. Including atmospheric chemistry and as input in determination of groundwater recharge using the chloride mass balance (CMB) technique.

Dataset History

The chloride deposition rate dataset is developed from 291 field observations of chloride in rainfall across Australia spanning a period of 75 years. These point data were interpolating to a gridded surface at a resolution of 0.05° x 0.05° using a four parameter function derived by Keywood et al. (1997) and a pilot point regularisation approach within PEST (Doherty, 2005). The uncertainty in the chloride deposition rate surface was quantified using the mean, standard deviation and skewness derived from null-space Monte Carlo analysis (Tonkin and Doherty, 2009) of 791 equally well-calibrated models.
