The CAMS services for Europe ('Regional production') provide pollen forecasts during pollen seasons. Please be aware that pollen forecasts are available during a specific period depending on the type of pollen (seasonal data). Dates below are for information only.
- Birch forecasts: from 1st March to 31st July (implemented November 2016)
- Grass forecasts: from 1st February to 31st August (implemented November 2016)
- Olive forecasts: from 1st January to 30th June (implemented November 2016)
- Ragweed forecasts: from 1st June to 31st October (to be implemented in June 2019). In principle, the season starts in midsummer: the 2 main driving parameters are the temperature and the photoperiod. A minimum of daily mean temperature is required and too long photoperiod slows down the phenological development. So, the shortening of photoperiod is used in models as a threadhold for the season start (end of July in Eastern and South-eastern Europe). The models will deliver datasets from 1st June, but data are expected to be null since midsummer.
This applies to both the individual models and the Ensemble.
Data can be accessed through the CAMS Regional website (Under Data Download/Archives then make sure Forecast type of data is selected).
All associated documentation and validations can be accessed through the main CAMS website: http://atmosphere.copernicus.eu/documentation-regional-systems
