Abstract
The dry deposition of ozone to a coniferous forest in northeastern Bavaria (southern Germany) was quantified during 1999 with both the eddy correlation method and a big leaf model. The model included parameterizations of the atmospheric transfer resistances from direct measurements, stomatal resistance from a plant ecological model, and an estimation of the cuticle resistance as function of leaf wetness. Early in the season, the measured and the modeled deposition fluxes were in good agreement, although the modeled fluxes tended to underestimate the measured ones. This underestimation was more pronounced in the late summer, when high nocturnal fluxes were frequently measured. The model parameterization of the cuticle and the stomatal resistances did not allow for such high fluxes. In these cases, the 24 hour average of the measured fluxes were up to 4.5 times higher than the modeled ones. The reasons for these large discrepancies remain unknown. However, assigning the unaccounted part of the deposition to a non-stomatal surface deposition pathway, a new parameterization of the respective resistance yielded an average value of 300 s m-1. It exhibited a decreasing trend through the vegetation period.
