This document outlines the role and responsibilities of the Atmospheric Observation Panel for Climate (AOPC), established by the GCOS Steering Committee and co-sponsored by the World Climate Research Programme (WCRP). The AOPC provides scientific and technical input on atmospheric climate observations and works to improve the global observing system. Supported by the WMO Integrated Global Observing System (WIGOS), AOPC aims to plan, monitor, and promote high-quality, long-term atmospheric observations for climate. The document details the panel's terms of reference, including maintaining essential climate variables, identifying gaps, and coordinating with stakeholders to ensure sustainable data collection and accessibility.
