Cala lies roughly 330 km northeast of Gqeberha. Cala's position between the Cape's winter rains and the summer-rainfall interior means vehicle traffic and mixed farming and light industrial activity are the dominant local pollution sources. This transitional climate usually supports decent dispersal, aside from the occasional calm, dry stretch. It's a fairly standard picture for this transitional climate zone.

When is air pollution at its worst in Cala?
Winter's lower rainfall is when air quality dips most at Cala, letting dust and emissions tied to mixed farming and light industrial activity persist longer than in wetter months. Conditions generally improve from spring through summer as rainfall increases and pollutants clear more readily, a seasonal pattern typical of this Eastern Cape climate zone.
Are air quality levels in Cala 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.
