Arad's air quality reflects its position on the flat Pannonian plain near the Romanian-Hungarian border at the Mureș river crossing, with vehicle traffic on the A1 motorway and the surrounding automotive and light manufacturing industry contributing local sources. The flat Banat-Crișana plain generally allows reasonable wind dispersal on most days, while winter residential heating and temperature inversions contribute seasonal PM2.5 elevation, and Arad's western Romania position exposes it to relatively cleaner Atlantic and Pannonian airflows compared to eastern Romanian cities.

Is air quality bad in Arad right now?
On 10 August 2026, overall air quality in Arad is poor. AQI is the main air quality indicator at 66.6/100. Pollution peaks around 11:00 PM (NO2: 66.6/100).

When is air pollution at its worst in Arad?
Arad residents notice reduced air quality mainly when poplar and linden pollen peaks, and during spells of vehicle traffic on the A1 motorway and the local automotive and light manufacturing industry; a change of season or a spell of wind usually clears things up again.
Are air quality levels in Arad 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.
