About pollen monitoring
RNSA & Copernicus (CAMS) — pollen monitoring in France
Pollen levels come from the Réseau National de Surveillance Aérobiologique (RNSA) and the European Copernicus service (CAMS, via Open-Meteo). The values show the concentration of pollen grains per cubic metre of air, graded Low, Moderate, High or Very high.
