Abstract

Long-Term SOi and NFb Flux Measurements and Their Application Invited contribution by the coordinator of subproject BIATEX-2 David Fowler*, Chris R. Flechard*, Jan-Willem Erisman^ and Gerald Spindler ^Institute of Terrestrial Ecology, Bush Estate, Penicuik, Midlothian EH26 OQB, UK ^Energieonderzoek Centrum Nederland, P.O.

V., Permoserstr. 15, 04303 Leipzig, Germany Summary Measurements of land-surface exchange of trace gases and pollutants at the field scale have, until recently, been based on campaign studies. The extrapolation to annual time scales and regional spatial scales have relied entirely on models in which the exchange at the surface is greatly simplified. Continuous measurements of SO: and NHs fluxes at three sites in Europe (southern Scotland, central Netherlands and S.E. Germany) have provided a unique oppor
