Spatial analysis and mapping the annual mean concentrations of acidity and major ions in precipitation over the United Kingdom in 1986

摘要: The composition of precipitation is being monitored in collectors sited throughout the United Kingdom. In first year, 1986, hydrogen ion, nitrate, ammonium and non-marine sulphate were measured samples from 47 sites annual mean concentrations determined. Spatial analysis based on Regionalized Variable Theory revealed autocorrelation all four ions reasonable bounded models fitted to sample variogram four. These then used estimate values a fine mesh grid by simple kriging, estimates contoured. estimation errors similarly mapped, both sets maps are presented. show that these greatest eastern parts country, as expected consideration European emissions weather patterns. For time also mapped how network could be improved.
