The IGAC International Project Office (IPO) staff works with the international atmospheric science community to implement the organizations priorities and activities set forth by an volunteer Scientific Steering Committee (SSC). The committee is currently comprised of sixteen research scientists from around the world. The IGAC liaisons are representatives of organizations that share IGAC's mission. Many IGAC activities and events are held jointly with these organizations. IGAC welcomes nominations and self-nominations to its SSC from the international scientific community. IGAC is currently accepting nominations for the 2020 SSC. Nominations will be accepted until 15 March 2019.
