About Arlington Air Quality
Arlington, Texas is home to approximately 398,121 residents. Air quality data for Arlington comes from OpenWeather's global atmospheric monitoring, which combines satellite observations and atmospheric models to track pollutants including PM2.5, PM10, ozone (O₃), nitrogen dioxide (NO₂), carbon monoxide (CO), and sulfur dioxide (SO₂).
The Air Quality Index (AQI) is calculated based on the pollutant with the highest concentration relative to EPA standards. An AQI value of 0-50 represents good air quality, 51-100 is moderate, and values above 100 indicate unhealthy conditions for sensitive groups or the general population.
View the current AQI for Arlington above to make informed decisions about outdoor activities, exercise, and health precautions. Our data is updated hourly to provide the most current information.
Understanding Air Quality in Arlington
Common Pollutants in Arlington
Air quality in Arlington is primarily affected by six key pollutants tracked by environmental monitoring systems. PM2.5 (fine particulate matter) consists of tiny particles less than 2.5 micrometers in diameter that can penetrate deep into lungs and even enter the bloodstream. PM10 (coarse particles) includes dust, pollen, and mold spores that can irritate airways.
Ground-level ozone (O₃) forms when pollutants from vehicles and industry react with sunlight, often peaking during warm, sunny days. Nitrogen dioxide (NO₂) mainly comes from vehicle emissions and power plants. Carbon monoxide (CO) results from incomplete fuel combustion, while sulfur dioxide (SO₂) primarily originates from industrial facilities and power generation.
Factors Affecting Arlington's Air Quality
Several factors influence air quality in Arlington throughout the year. Weather patterns play a crucial role—temperature inversions can trap pollutants close to the ground, while wind helps disperse them. Humidity levels affect how certain pollutants form and behave in the atmosphere.
Traffic patterns significantly impact local air quality, with rush hours typically showing elevated pollutant levels. The city's geography, including proximity to industrial areas, major highways, and natural features, creates unique air quality patterns. Seasonal variations are also important—summer heat can increase ozone formation, while winter heating may raise particle pollution levels.
When to Check Air Quality in Arlington
Residents of Arlington should check air quality before planning outdoor activities, especially if you have respiratory conditions, are pregnant, or have young children. Morning checks are ideal for planning your day's activities. It's particularly important to monitor AQI during wildfire season, high-traffic events, temperature inversions, or when you notice hazy conditions. Athletes and outdoor workers should check conditions before extended outdoor exposure.
