Objective
To continue and extend the work initiated successfully with SREMP "Surface Resistence Emergency Measurement Program" at a larger variety of ecosystems situations, including in the measurements pollutants such as NOx and HNO3 which have an important role in the acidification and eutrophication of European ecosystems.
Anthropogenic air pollutants are transported at long distances in Europe affecting rural ecosystems by direct
attack of oxidants such as ozone on vegetation and through deposition of acidity and nutrients. The application
of the critical loads concept to assess the effects of air pollutants and to the management of air quality in Europe
requires the precise knowledge of dry deposition processes and mechanisms in order to preview with certainty
transportation from emission sources and deposition over the different European ecosystems.
During BIATEX Workshops it was recognised that a large amount of data has been gathered during last years
for Europe which resulted in a better and more accurate parameterisation of dry deposition fluxes, but also that
an almost complete lack of information still exists concerning dry deposition for conditions prevalent in South
Europe, completely different from northern European regions, with extensive periods of dry and warm weather
which result in drying and dying of herbaceous vegetation during Summer. Parameterisation of dry deposition
processes, developed with flux measurements taken in northern Europe have to be tested for these different
ecosystem characteristics, before its application in long range transport models and the preparation of dry
deposition maps can be done with confidence. Measurements taken along extensive periods in SREMP, in
1994/1995 will give valuable but incomplete information concerning dry deposition processes in Southern
Europe because it only addressed a limited number of pollutants and ecosystem types. Measurements will be
made at 4 to 8 different sites, with variable vegetation coverage characteristics, in the Iberian Peninsula and at
2 to 4 locations in Italy and over a pine forest in Southwest Europe. Automatic measuring stations will be
employed to determine micro meteorological parameters and to measure dry deposition fluxes by the gradient
and eddy correlation methods. The obtained information will permit a better quantification of oxidant, acidic
and nutrient fluxes in South European ecosystems and also the calibration of existent dry deposition
parameterisation algorithms which can then be applied with confidence to both North and South European
conditions. The results will be particularly relevant to the next phases of sulphur and nitrogen protocols prepared
by EMEP, because by reducing uncertainties associated with deposition, better estimates of import and export
of pollutants in Europe can be calculated.
