Casco Antiguo (Segovia)'s air quality is shaped mostly by light construction dust and seasonal heating smoke in winter. Air quality is generally moderate, dictated mostly by how much traffic reaches the old core. Pedestrianised zones in many old centres have measurably reduced local traffic pollution.

When is air pollution at its worst in Casco Antiguo (Segovia)?
How do the seasons affect air quality in Casco Antiguo (Segovia)? The winter months typically bring the weakest air quality of the year, as calm anticyclonic conditions trap vehicle and heating pollution near the surface. Conditions tend to ease in spring, as more active weather systems bring the wind and rain needed to disperse ground-level pollution. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. By late autumn, air quality is usually back to more moderate levels, though the first cold snaps can bring an early hint of winter's traffic and heating pollution. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.
Are air quality levels in Casco Antiguo (Segovia) 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.
