SPARC
SPARC (Stratospheric Processes And their Role in Climate) is a core project of the World Climate Research Programme which coordinates international efforts to bring knowledge of the stratosphere to bear on relevant issues in climate variability and prediction. SPARC themes and activities address areas of societal concern such as: climate variability and change, ozone, atmospheric chemistry and aerosols, and polar processes. Find more information on SPARC web sites.
IO3C
The IO3C (International Ozone Commission) was established in 1948 as one of the special commissions of the International Union of Geodesy and Geophysics, who represent the entire community of geophysical scientists around the world. The purpose of the IO3C is to help organize the study of ozone around the world, including ground-based and satellite measurement programs and analyses of the atmospheric chemistry and dynamical processes affecting ozone. For more information see IO3C web sites.
IGACO-O3
The Atmospheric Chemistry Theme Report on Integrated Global Atmospheric Chemistry Observations (IGACO) was published in 2004. The IGACO report provides a rationale for integrated global air chemistry observations, an assessment of observational capacity and recommendations that highlight what is needed to build an integrated atmospheric chemistry observational system. In addition, it emphasizes the role of ozone as a key component of the atmosphere and the Earth system. The IGACO-O3/UV Office was established in 2005 for supporting the GAW Scientific Advisory Groups for Ozone and for UV in developing and carrying out this implementation plan and facilitating activities that serve to integrate observations and yield useful services and products. For more information on the topic see IGACO-O3 web sites.
NDACC
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 the 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.
