Copernicus: First automated pollen measurements allow cross-checking forecasts in several European countries in near-real-time
The Copernicus Atmosphere Monitoring Service (CAMS) today announces the first step in a joint initiative with the European Aeroallergen Network (EAN) to automated pollen monitoring in several European countries. Under the auspices of the Network of European National Meteorological Services (EUMETNET), various pollen monitoring sites have been equipped with automated observation capability as part of the “Autopollen” […]
New website pollenscience.eu
The aim of the Pollen Science website is to collect and graphically display the data of different measuring networks and stations for pollen flight in a database. This makes it easy and interactive to determine when and how many pollens of the different species are currently measured in the air or when they have been […]
Different techniques to identify pollen.
As pollengrains are very, very small and are floating through the air, identifying them is a pretty difficult job. You’ll can use a microscope to identify the type of pollen. Pollengrains are not like fashionmodels who can stand still and wait for the phototgrapher to take shot. So often the pollengrains are collected by a […]
Process of Automatic Pollencounting
The process starts bottom left with trees, grasses or herbs producing pollen, which become airborn. Step 1. Collect & fix pollen Collecting these pollen from the air with some kind of vacuum cleaner. Of course the volume of air processed in a certain period of time is important since you want information about the concentration […]

Pollencount by hour
This graph is an example of pollenconcentration during three different types of days. Day 1 shows airborn pollen between 9:00 and 17:00. Day 2 shows a pollenpeak during the early morning hours. Day 3 shows a peak in the evening. Weatherconditions, like a rainshower, a sunny or cloudy day, have big influence on the hourly […]
Ambrosia
About Ambrosia Ragweeds are flowering plants in the genus Ambrosia in the aster family, Asteraceae. They are distributed in the tropical and subtropical regions of the New World, especially North America, where the origin and center of diversity of the genus are in the southwestern United States and northwestern Mexico. Several species have been introduced […]
Tree calendar
This calendar shows when specific trees are flowering (in the Netherlands). The calendar is video-based. Every tree is explained by a short video. Corylus aveilana Alnus incana Alnus glutinosa Salix viminalis Taxus Bacatta Populus x more Carpinus Betulus Betula pendula more information >> Fagus sylvatica Quercus robur […]
Grass calendar
This example calendar shows when specific grasses are flowering (in the Netherlands). The calendar is video-based. Every grasstype is explained by a short video. Alopecurus pratensis Image: Alopecurus pratensis, Meadow foxtail. Five stages in ripening of the inflorescense and opening of the anthers to free pollen. more information >> Dactylis glomerata Poa pratensis Anthoxanthum odoratum […]
Winddirection and pollenpressure
Are winddirection, pollenconcentration and pollenpressure correlated? It very much depends on your location. This graph shows that for the Netherlands a south-east wind is less favourable, as it can bring pollen from Germany and Belgium. When you live on a small island like Helgaland, every winddirection is favourable. Besides winddirection also windspeed is correlated.
