Global Atmosphere Watch
One of the core tasks of the GAW programme is the coordination of the activities and data of currently 30 global and more than 400 regional atmospheric research stations to produce data that are relevant to climate change.
GAW at Empa
The mission of WCC-Empa and QA/SAC Switzerland is to improve and maintain the quality and public access of surface ozone, carbon monoxide, methane and carbon dioxide data measured at Global Atmosphere Watch stations, primarily through system and performance audits at GAW stations, inter-comparison and calibration of instrumentation, one-to-one training and workshops, as well as continuous operational and strategic support for the GAW programme, in order to contribute to the scientific basis of our understanding of climate change.
Currently (2011-2016), the GAW team at Empa is also involved in the CATCOS (Capacity Building and Twinning for Climate Observing Systems) project that is funded by the Swiss Agency for Development and Cooperation (SDC) with MeteoSwiss as the coordinating partner. Within CATCOS, Empa is responsible for the implementation of greenhouse gas observation capabilities in Vietnam, Chile and Kyrgyzstan & associated twinning / support.
