Cooperation with other networks and institutions

The international Network for the Detection of Atmospheric Composition Change (NDACC) is composed of more than 100 globally distributed, ground-based, remote-sensing research stations with more than 160 currently active instruments. The NDACC Objectives are:

• to establish long-term databases for detecting changes and trends in atmospheric composition and to understand their impacts on the mesosphere, stratosphere, and troposphere;
• to establish scientific links and feedbacks between changes in atmospheric composition, climate, and air quality;
• to validate atmospheric measurements from other platforms (i.e. satellites, aircraft, and ground-based platforms);
• to provide critical data sets to help fill gaps in satellite observations;
• to provide collaborative support to scientific field campaigns and to other chemistry and climate-observing networks; and
• to provide validation and development support for atmospheric models.

The NDACC began network operations as The Network for Detection of Stratospheric Change (NDSC) in January 1991.
