Short description: The paper presents the precipitation and runoff data over a 17 year period from a forest roof experiment at Risdalsheia, southern Norway. A 1200 m2 roof placed over the forest canopy excluded about 80% of ambient acid deposition, while clean rain was sprinkled under the roof. A climate change treatment (a 3.7 degrees increase in air temperature and an increase in air carbon dioxide concentrations to 560 ppmv) was superimposed on the clean rain treatment for four years (1995-1998). Sea-salt inputs and temperature are climate-related factors that influence water chemistry and can confound long-term trends caused by changes in deposition of sulphur and nitrogen. The RAIN and CLIMEX experiments at Risdalsheia provided direct experimental data that allow quantitative assessment of these factors.
