Online lectures for the 7th Joint Training Course on Atmospheric Composition hosted by @ecmwf.int , CAMS, @eumetsat.int and @esa.int start next week (1–2 & 9–10 Oct 2025) and are open to all. Lectures cover observations, modelling and monitoring of aerosols and air quality.

A challenging summer for air quality saw the highest wildfire emissions in 23 years in Europe & the UK, driven by wildfires in Iberia. CAMS data also revealed repeated episodes of transatlantic smoke, Saharan dust and ozone spikes. Read the article: atmosphere.copernicus.eu/highest-wild...
