3) To advocate for the establishment, re-establishment and maintenance of integrated systems to provide long-term, high-quality, consistent data and information to meet those requirements according GCOS monitoring principles;
4) To propose and promote the establishment of new systems, or enhancements to current systems and practices, to address deficiencies;
5) To review the current state and identify gaps and inadequacies of the atmospheric component of the global observing system;
6) To promote the establishment of sustainable observation networks and the use best practises;
7) To promote the rehabilitation of relevant historical data sets;
8) To promote and review institutional arrangements to ensure that climate data and observations are:
of the highest quality based on agreed metrics;
