Humans and ecosystems are only as healthy as the atmosphere in which we live. Tracking atmospheric constituents like air pollutants, stratospheric ozone, and greenhouse gases improves our knowledge and resilience. 🌫️🌋🌍 The Global Atmosphere Watch Programme provides trusted, long‑term observations of atmospheric composition. These measurements power forecasting models and early warnings that help communities prepare for hazards like dust storms, forest fire smoke plumes, and volcanic eruptions. #GAW #WMO #AirQuality #GreenhouseGases #EarlyWarnings #ScienceforAction #stratosphericozone
