Mission's air quality in Texas reflects the lower Rio Grande Valley's agricultural and border city character, with vehicle emissions from US-83 and the surrounding citrus and vegetable farming and maquiladora operations contributing local sources. Gulf of Mexico southeasterly breezes provide reliable warm-season ventilation, while cross-border agricultural burning from Tamaulipas and McAllen-Mission metropolitan traffic contribute the primary regional air quality influences.

Is air quality bad in Mission right now?
On 9 August 2026, overall air quality in Mission is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 12:00 AM (PM10: 100/100).
Will air quality be worse tomorrow in Mission?
On 10 August 2026, air quality conditions in Mission will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 6:00 AM (PM10: 100/100).
When is air pollution at its worst in Mission?
Mission's air quality follows a clear seasonal pattern: spring and autumn generally bring more moderate, cleaner conditions between the extremes of summer and winter cedar season, but intense summer heat drives persistent ozone problems, particularly in and around the largest metro areas. Dust from West Texas can occasionally drift across the state and add to particulate levels.
Are air quality levels in Mission 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.
