The International and Interagency Affairs office (IIA) establishes policies and practices with regard to NOAA Satellite and Information Service-related bilateral and multilateral cooperation.  It supports program offices and NOAA management in developing partnerships with foreign counterpart space and international user organizations as well as with U.S. Government agencies.

The Office negotiates Memoranda of Understanding and letter agreements with foreign and other Federal agencies in support of NOAA and U.S. Government (USG) interests; in particular, to ensure continued foreign instrument contributions to NOAA satellites and cost sharing provision of satellite services; to obtain full operational access to foreign satellite and ground-based data; and to actively promote international acceptance of the U.S. data policy of full and open international data sharing. The Office provides international and interagency policy- level support to NOAA Satellite and Information Service Offices and Centers and to NOAA senior officials. It develops, coordinates and presents NOAA and USG positions in connection with a number of international coordination mechanisms including the intergovernmental Group on Earth Observations, the Committee on Earth Observation Satellites and the Coordination Group on Meteorological Satellites.

In the U.S. interagency arena, the Office represents NOAA in the development of U.S. national space policies, and in the coordination of environmental coordination of international activities under the U.S. Group on Earth Observations.
