Open-Meteo + CAMS
Public keyless API for non-commercial use. PollenTotal requests CAMS European pollen variables and computes each day's hourly maximum in the browser.
Real observations come from stations and networks with their own methods, publication schedules and access terms. PollenTotal links to their official resources without relaying or mixing counts with the CAMS forecast.
