Air quality in the Canary Islands (Spain), as well as in Madeira (Portugal), has been heavily affected by significant concentrations of particulate matter (dust) in the air. Consequently, the Spanish National Meteorological Agency, AEMET, has issued a yellow alert and health authorities have advised people not to stay outdoors for extended periods of time.
With a revisit time of one day, the Copernicus Sentinel-5P satellite delivers free and open access data that can be used to monitor air quality worldwide. This data can be used to inform models that predict the impact of dust storms.
