Worst air pollution Krimpen aan den IJssel, today and tomorrow

On 9 August 2026, overall air quality in Krimpen aan den IJssel is fair. PM1 is the main pollutant at 21.2/100. Pollution peaks around 4:00 PM (O3: 48.1/100).

On 10 August 2026, air quality conditions in Krimpen aan den IJssel will be similar to today, with AQI forecast at fair at 25.6/100. Pollution peaks around 11:00 AM (O3: 25.6/100).

Keep an eye on Krimpen aan den IJssel during the birch, oak, and alder pollen peak over the spring and early-summer period, and on calm, hot days when traffic on the A16 and local industry emissions accumulate; the flat polder terrain and sea proximity generally support decent air movement. Most weeks outside these periods bring Krimpen aan den IJssel conditions close to the broader Dutch norm.

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.
