Stratosphere-troposphere Processes And their Role in Climate (SPARC) is a core project of the World Climate Research Programme.
Founded in 1992, SPARC has coordinated high-level research activities related to understanding Earth system processes for over two decades. More specifically, SPARC promotes and facilitates cutting-edge international research activities on how chemical and physical processes in the atmosphere interact with climate and climate change.
