The Community

IGAC's structure consists of its parent organizations, IGBP and iCACGP, the IGAC SSC, and the IGAC Offices. However, the true IGAC community is the more than 3,000 scientists, students, policy makers, stakeholders, and general public from across six continents that make up the IGAC community. It is this international community that gives IGAC its unique ability to truly function without borders and implement its vision to coordinate and foster atmospheric chemistry research towards a sustainable world.
