Zusammenfassung |
Dry deposition to the Earth's surface is an important process from
both an atmospheric and biospheric perspective. Dry deposition
controls the atmospheric abundance of many compounds as well as their
input to vegetative surfaces, thus linking the atmosphere and
biosphere. In many atmospheric and Earth system models it
is represented using "resistance in series" schemes developed in the
1980s. These methods have remained relatively unchanged since their
development and do not take into account more recent understanding of
the underlying processes that have been gained through field and
laboratory based studies. In this study we compare dry deposition of
ozone across 15 models which contributed to the TF HTAP model
intercomparison to identify where differences occur. We compare
modelled dry deposition of ozone to measurements made at a variety of
locations in Europe and North America, noting differences of up to
a factor of two but no clear systematic bias over the sites
examined. We identify a number of measures that are needed to provide a
more critical evaluation of dry deposition fluxes and advance model
development. |
