A research project of
Academy of Finland
objectives of the project are:
(i) to develop an integrated modelling system for simulating and forecasting
in time the pollen emissions and transport on an European scale; and
(ii) to evaluate the spatial distributions of pollen emissions and
concentrations in Europe.
project will concentrate on:
(i) the development, evaluation and implementation in numerical model of a
unified parameterization of the birch pollen emissions over Europe;
(ii) the modelling of the characteristics of pollen grains (as a special
case of atmospheric aerosol);
(iii) the utilisation of the satellite and ground-based data for improved
real-time modelling of pollinating seasons;
(iv) the numerical simulations of the regional and continental spatial
distribution of airborne birch pollen in Europe; and
(v) the evaluation of the accuracy and reliability of the developed
modelling system, by comparing model predictions with the phenological and
aerobiological, and other available experimental data. We have selected
birch pollen as the first example pollen species, due to substantial health
effects for the population, and its ability to be transported over
The system will be based on
the Finnish Emergency modelling system, SILAM,
and will include also various phenological models describing the pollinating
seasons of birch.
|January 2007. The annual project meeting will take place in Helsinki 15-16.01.2007.
The meeting agenda is available. |
|December 2006. The development of pollen episode during April-May 2006 is available.
The movie shows the concentrations of fine particles emitted from anthropogenic sources (left-hand panel), the fine particles emitted from biomass burning (wild-land fires, middle panel), and birch pollen from the European birch forests (right-hand panel).
|March 2006. 2006 pollen forecasts have been started (see internal pages for results).
So far, the model configuration is the same as in 2005.|
|November 2005. Project annual meeting is scheduled to 23-24.01.2006
Agenda is being compiled. Suggestions are welcome (send to: mikhail.sofiev (at) fmi.fi).|
|September 2005. Project working meeting on the status update and
emission model development. See Archive for the meeting minutes.|
