Does pollen in Winchester come from nearby or far away?

A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Winchester based on measurements or forecasts?

This allows us to estimate pollen levels for today and the coming days, not just report the past.
