The AMS Policy Program focuses on three approaches: 1) we develop capacity within the scientific community for effective and constructive engagement with the broader society; 2) we inform policy makers directly of established scientific understanding and the latest policy-relevant research; and 3) we help expand the knowledge base needed for incorporating scientific understanding into the policy process through research, analysis, and studies. Through our activities, we seek to ensure that policy choices take full advantage of information and services relating to weather, water, and climate and to help policy makers understand how much the broader society's welfare depends on information and services relating to weather, water, and climate. This will help ensure that the scientific community receives the support and resources it needs to be able to make critical information and services available and, most importantly, will help the nation, and the world, avoid risks and realize opportunities related to the Earth system.
