Valašské Meziříčí's setting where the Rožnovská and Vsetínská Bečva rivers meet means vehicle traffic and light industry in the river valley drives most of the local variation in air quality across the year. The Zlín Region terrain nearby can trap emissions under stable conditions, though stronger winds or rainfall usually bring noticeable improvement, and residents typically notice the clearest air during the more unsettled, windier stretches of the year.

When is air pollution at its worst in Valašské Meziříčí?
The clearest dips in Valašské Meziříčí's air quality track oak and hornbeam pollen peaks and periods of vehicle traffic and light industry in the river valley; the rest of the year typically brings clearer, more consistent conditions for the Zlín Region area, particularly once autumn winds set in and the local terrain ventilates more easily than during calmer stretches.
Are air quality levels in Valašské Meziříčí based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
