Australian chloride deposition rate

Brief description

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.
Lineage: 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.
