UT/LS ozone GASP MOZAIC aircraft programs ozonesondes
2009/8/7
We present ozone measurements of the Global Atmospheric Sampling Program (GASP) performed from four commercial and one research aircraft in the late 1970s to compare them with respective measurements ...
Long-term changes in the water quality of rainfall, cloud water and stream water for moorland, forested and clear-felled catchments at Plynlimon, mid-Wales
Calcium aluminium ammonium pH
2009/3/24
Long term changes in the water quality of rainfall, cloud water and stream waters draining acidic and acid sensitive moorland and forested catchments at Plynlimon, mid-Wales, are examined for the per...
Long-term changes in acidification and recovery at nine calibrated catchments in Norway, Sweden and Finland
acidification recovery Scandinavia
2009/3/23
International agreements to reduce the emissions of acidifying pollutants have resulted in major changes in deposition of sulphur and nitrogen in southern Scandinavia over the past 25 years. Long-term...
Modelling long-term changes in stream water and soil chemistry in catchments with contrasting vulnerability to acidification (Lysina and Pluhuv Bor, Czech Republic)
MAGIC model catchment critical loads Gothenburg Protocol
2009/3/12
In two Czech catchments covered by Norway spruce forests, the MAGIC model was used to simulate annual stream water and soil chemistry for the period 1851–2030. These two sites represent geochemical en...
