NDACC Goals and Organization
The primary goal of the Network for the Detection of Atmosphere Composition
Change (NDACC) is to obtain high quality measurements of a broad range of
atmospheric chemical species and parameters. The initial objective of the NDACC
was to make observations through which changes in the physical and chemical
state of the stratosphere could be determined and understood. While the network
remains committed to monitoring changes in the stratosphere, with an emphasis
on the long-term evolution of the ozone layer (its decay, likely stabilization
and expected recovery), its priorities have broadened considerably to encompass
- Detecting trends in overall atmospheric composition and understanding their
impacts on the stratosphere and troposphere,
- Studying atmospheric composition variability at interannual and longer
timescales,
- Establishing links and feedbacks between climate change and atmospheric composition,
- Calibrating and validating space-based measurements of the atmosphere,
- Supporting process-focused scientific field campaigns, and
- Testing and improving theoretical models of the atmosphere.
The NDACC is an international activity, involving and requiring the
participation of scientists around the world. It has been endorsed by the
United Nations Environment Programme (UNEP) and the International Ozone
Commission (IOC) of the International Association of Meteorology and
Atmospheric Physics and by the World Meteorological Organization (WMO)
as a major contributor of WMO’s Global Atmosphere Watch (GAW).
The NDACC Steering Committee consists of two
co-chairs, pairs of PIs representing each of the Working Groups, Independent
Scientists who are appointed to act as peer reviewers, and ex-officio members
from important NDACC funding agencies.
To ensure quality and consistency of NDACC operations and products, a number
of protocols have been formulated covering such topics
as primary and complementary measurements, data, instruments inter-comparisons,
theory and analysis, and validation.
