Pan-European initiative to provide pollen forecasts based on near real-time observations

The Copernicus Atmosphere Monitoring service (CAMS) recently formed a new partnership with the European Aeroallergen Network (EAN,) and will explore ground breaking technology to deliver automatic pollen observations in near real-time across Europe. Every year during spring and early summer comes a chorus of sneezing, wheezing and sniffling, because this is peak hay fever season […]

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 […]

The Birch is not the first trees in the season which flowers, but it has highly allergenic pollen. Although there is a flowering-calendar which indicates the usual period of flowering, you can see in the graph this can vary a lot. In 2017 there was a birchpollen peak (in the Netherlands) at the end of […]

Grasspollen concentration by day

There are several types of grass which release allergenic pollen, like rye, timothy, orchard and bermuda, but also corn pollen can cause problems. You can see in the graph below that the flowering period (in the Netherlands) starts early may and lasts until the end of july. About Grasses Poaceae or Gramineae is a large […]
