An Integrated Information System (IIS) is a proven, whole-of-government organizational approach for enabling and strengthening capabilities to understand, manage, and mitigate societal risks from complex environmental hazards (e.g., heat, drought, floods). These systems work across sectors, timescales, geographies, and disciplines. An IIS is designed to inform and improve the policy and decision-making landscape, connect and amplify existing programs and networks, and respond to emerging priorities in a rapidly changing climate.

This fact sheet covers why we need Integrated Information Systems, why they exist, and how they work. It also provides specific examples from NOAA's National Integrated Drought Information System (NIDIS), National Integrated Heat Health Information System (NIHHIS), and National Integrated Flood Information System (NIFIS).
