| Zusammenfassung |
Simulating pollen concentrations with numerical weather prediction
(NWP) systems requires a parameterization for pollen emission. We
have developed a parameterization that is adaptable for different
plant species. Both biological and physical processes of pollen
emission are taken into account by parameterizing emission as
a two-step process: (1) the release of the pollen from the flowers,
and (2) their entrainment into the atmosphere. Key factors
influencing emission are temperature, relative humidity, the
turbulent kinetic energy and precipitation.
We have simulated the birch pollen season of 2012 using the NWP
system COSMO-ART (Consortium for Small-scale
Modelling – Aerosols and Reactive Trace
Gases), both with a parameterization already present in
the model and with our new parameterization EMPOL. The statistical
results show that the performance of the model can be enhanced by using
EMPOL. |
