Network for the Detection of Atmospheric Composition Change 

Symposium celebrating 20 years of atmospheric research
fostered by NDACC/NDSC observations

Réunion Island
7-10 November 2011

The international Network for the Detection of Atmospheric Composition Change (NDACC) is composed of more than 70 high-quality, remote-sensing research stations for observing and understanding the physical and chemical state of the stratosphere and upper troposphere, and for assessing the impact of stratosphere changes on the underlying troposphere and on global climate. While NDACC remains committed to monitoring changes in the stratosphere with an emphasis on the long-term evolution of the ozone layer, its priorities have broadened considerably to encompass issues such as the detection of trends in overall atmospheric composition and understanding their impacts on the stratosphere and troposphere, and establishing links between climate change and atmospheric composition. Following five years of planning, instrument design and implementation, the NDACC began network operations in January 1991 as the NDSC.

Expanding on the symposium celebrating the first 10 years observations held in Arcachon in 2001, this symposium takes the opportunity of the opening of the new high altitude Maido observatory in Reunion Island in the southern tropics for celebrating the 20 years atmospheric research fostered by observations of the network. 

Opening of Maido Observatory

Symposium attendees will be given an opportunity to visit the Maido observatory currently under construction, which is scheduled to begin operations in early 2012.

The symposium will be followed by a one-day meeting of
the NDACC Steering Committee on 11 November 2011
