Palencia's air quality benefits from the elevated Castilian Meseta position at 734 metres on the flat Carrión river plain, with consistent winds across the open Palencia plateau providing generally good dispersal. Vehicle traffic on the A-67 and surrounding agricultural and light manufacturing contribute local sources, while the open Castilian plain and the prevailing westerly winds generally prevent significant pollution accumulation in this quiet Castilian capital throughout the year.

When is air pollution at its worst in Palencia?
What is the yearly air quality pattern like in Palencia? Winter is generally the most challenging season, since low wind speeds and temperature inversions prevent traffic and wood-smoke pollution from dispersing. Conditions generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. Being inland, this area sees more extreme summer heat and winter cold, which sharpens the seasonal contrast in air quality.
Are air quality levels in Palencia 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.
