Global Climate Observing System (GCOS)

The Global Climate Observing System (GCOS) is an international program that monitors Earth's climate to understand changes over time. It collects and shares important data, such as temperature, rainfall, and greenhouse gas levels, from various sources like satellites and ground stations. This information helps scientists analyze climate trends, predict future changes, and inform policy decisions to address climate issues. By ensuring consistent and reliable climate data, GCOS supports efforts to manage climate impacts and enhance global understanding of the climate system.
