Global Atmosphere Watch

Definition

The Global Atmosphere Watch (GAW) is an initiative by the World Meteorological Organization (WMO) designed to monitor and assess the state of the Earth's atmosphere. It aims to provide accurate and timely data on atmospheric composition, climate change, and air pollution, which are crucial for understanding and addressing environmental challenges. Through a network of observation stations and research programs, GAW supports efforts to improve atmospheric science and inform policy decisions related to air quality and climate.
