Are pollen levels in Walton upon Thames based on measurements or forecasts?

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Walton upon Thames, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
