Science working Groups coordinate analysis and modeling efforts, and are responsible for planning IHY meetings, symposia and workshops through the three major thrusts:

1. Scientific Campaigns and CIPs: oversees the IHY Coordinated Investigation Programmes (CIPs). The team reviews proposals for IHY CIPs, coordinates the input from the scientists and observatory representatives, and maintains the IHY observing and campaign schedule.
2. Scientific Meetings and Publications: arranges for communication of scientific results to broader science community.
3. Public Outreach: responsible for increasing public awareness of IHY activities. This committee produces newsletters, maintains the website(s), writes articles, coordinates media affairs, and develops outreach products.
