| Zusammenfassung |
| Trajectory statistical methods that combine in situ measurements of trace gas
or particle concentrations and back trajectories calculated for corresponding
times have proven to be a valuable approach in atmospheric research;
especially in investigating air pollution episodes, but also in e.g. tracing
the air mass history related to high vs. low concentrations of aerosol
particles of different sizes at the receptor site. A concentration field
method was fine-tuned to take the presumable horizontal error in calculated
trajectories into account, tested with SO2 and validated by comparison
against EMEP (European Monitoring and Evaluation Programme) emission data. In
this work we apply the improved method for characterizing the transport of
atmospheric SO2, NOx, O3 and aerosol particles of different size
modes to a Finnish measurement station located in Hyytiälä
(61°51' N, 24°17' E). Our method did not reproduce the EMEP
emission soures, but proved useful for qualitative analysis on where the
measured compounds come from, from one measurement station point of view. We
applied it to study trends and seasonal variation in atmospheric pollutant
transport during 13 yr at the SMEAR II (Station for Measuring Ecosystem-Atmosphere Interactions) station. |
