Returns hourly surface concentrations from the CAMS European air-quality ensemble for a point in the cached DACH and Central Europe area. Available pollutants are CO, NO2, NO, O3, PM2.5, PM10 and SO2. Values come from the nearest 0.1 degree model cell and are labelled as a regional forecast rather than a street-level sensor reading. The local cutout is refreshed independently of paid calls, so Copernicus processing latency is not passed to the caller.Overview
