On 22 July 2026, air quality conditions in Weilheim in Oberbayern will be similar to today, with O3 forecast at fair at 35.8/100. Pollution peaks around 6:00 AM (NO2: 46.0/100).

In Weilheim in Oberbayern, air quality dips most noticeably when spruce, beech, and linden pollen peaks, or on warm, windless days when local pollution accumulates; everyday local traffic contributes a modest, fairly steady source. This warmer southern climate brings a modest late-summer ragweed presence from mid-August. Afternoon breezes usually clear out any buildup from the morning.

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.

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.
