| Zusammenfassung |
| In May 2003, severe forest fires in southeast Russia resulted in smoke
plumes extending widely across the Northern Hemisphere. This study combines
satellite data from a variety of platforms (Moderate Resolution Imaging
Spectroradiometer (MODIS), Sea-viewing Wide Field-of-view Sensor (SeaWiFS),
Earth Probe Total Ozone Mapping Spectrometer (TOMS) and Global Ozone
Monitoring Experiment (GOME)) and vertical aerosol profiles derived with
Raman lidar measurements with results from a Lagrangian particle dispersion
model to understand the transport processes that led to the large haze
plumes observed over North America and Europe. The satellite images provided
a unique opportunity for validating model simulations of tropospheric
transport on a truly hemispheric scale. Transport of the smoke occurred in
two directions: Smoke travelling northwestwards towards Scandinavia was
lifted over the Urals and arrived over the Norwegian Sea. Smoke travelling
eastwards to the Okhotsk Sea was also lifted, it then crossed the Bering Sea
to Alaska from where it proceeded to Canada and was later even observed over
Scandinavia and Eastern Europe on its way back to Russia. Not many events of
this kind, if any, have been observed, documented and simulated with a
transport model comprehensively. The total transport time was about 17 days.
We compared transport model simulations using meteorological analysis data
from both the European Centre for Medium-Range Weather Forecast (ECMWF) and
the National Center for Environmental Prediction (NCEP) in order to find out
how well this event could be simulated using these two datasets. Although
differences between the two simulations are found on small scales, both
agree remarkably well with each other and with the observations on large
scales. On the basis of the available observations, it cannot be decided
which simulation was more realistic. |
