Historic trends in N and S deposition in the UK1800 to present
data & model spatial distribution• Model time series of emissions & deposition• UK focus & European background• Analyse & interpret data• Publish results & collaborate on further work• Publish data
Present Day
• First population census data• Industrial Revolution
• Domestic coal use peak• Board of Agriculture established
• Large scale Haber-Bosch processing commences
• Increase in motor vehicles
Peak in sulphur emissions
• Peak NOx & NH3 emissions• Sulphur reducing
