| Abstract |
The SPARC Project (Stratospheric Processes And their Role in Climate), established within the WCRP (World Climate Research Programme) in 1992, deals with the role of the stratosphere in the climate of the "Troposphere-Stratosphere System". It was recognised at that time that, even though the stratosphere has been the subject of intense scientific studies for over two decades, how changes in the stratospheric composition may have an impact on the climate had not been given enough attention although they are an important component of the anthropogenic forcing of the climate.
In establishing SPARC, the Joint Scientific Committee for the WCRP asked the SPARC Scientific Steering Group (SSG) to identify the key scientific issues and the gaps in the on-going research in order to understand the impact of stratospheric dynamical, chemical and radiative processes on global climate.
