Pollen monitoring network
In late 2021, the Department of the Environment developed a network of sensors to monitor pollen with OBERON SCIENCES.
Allergen risk in the Principality
The measurements taken, when correlated with meteorological conditions, enable the allergen risk to be determined in accordance with the scale opposite.

Échelle de niveau de risque allergique
The main allergen sources are also identified and displayed.
In addition, a forecast of the allergen risk for the following day (D+1) and the day after that (D+2) is made, taking account of the weather forecast.
OBERON SCIENCES is a technology company spun out of CEA and CNRS, a partner in European pollen metrology projects , and a Greentech Innovation accredited company.
Advice
If you have allergies:
- Get at least 10 minutes of fresh air every day before sunrise and after sunset
- Avoid drying laundry outside
- Rinse your hair in the evening
- Keep car windows closed to prevent pollens from getting inside
