Since 2005 Empa calculates 10-day back-trajectories for a number of sites of the Global Atmosphere Watch (GAW) programme of the World Meteorological Organisation (WMO). These back-trajectories can given a first impression of the origin of air masses arriving at the sites and, hence, can be used to identify up-stream sources and events. Trajectories are calculated daily with a delay of about 2 days. For further questions and data requests, please contact Stephan Henne.
