NDACC Goals and Organization
The international Network for the Detection of
Atmospheric Composition Change (NDACC) was formed to provide a consistent, standardized
set of long-term measurements of atmospheric trace gases,
particles, and physical parameters via a suite of globally distributed
sites.
The principal goals of the network are:
- To study the temporal and spatial variability of atmospheric composition
and structure in order to provide early detection and subsequent long-term
monitoring of changes in the physical and chemical state of the stratosphere
and upper troposphere; in particular to provide the means to discern and
understand the causes of such changes.
- To establish the links between changes in stratospheric ozone, UV
radiation at the ground, tropospheric chemistry, and climate.
- To provide independent calibrations and validations of space-based sensors
of the atmosphere and to make complementary measurements.
- To support field campaigns focusing on specific processes occurring at
various latitudes and seasons.
- To produce verified data sets for testing and improving multidimensional
models of both the stratosphere and the troposphere.
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 intercomparisons,
theory and analysis, and validation.
