Air quality: Sentinel-5P satellite observation + CAMS model (Copernicus)

Air composition at any coordinate worldwide from Copernicus, in two layers. OBSERVATION (products): the latest Sentinel-5P TROPOMI satellite pass - NO2, O3, CO, CH4 and the UV aerosol index as COLUMN densities (not surface, not an air-quality index), each with its observation time; often null (a polar orbiter sees a place about once a day, clouds aside). MODEL (model): CAMS surface concentrations in ug/m3 - a continuous field that fills those gaps - cams_global (PM2.5, PM10 worldwide) and cams_european (CO, NO2, O3, SO2, PM2.5, PM10 over Europe). Modelled estimates, not measurements. Select observation products with the products parameter.
