19 October 2010:
New plots are added. Total number of sites is now 322.

Note:
Each plot shows three trajectories at different arrival heights. For sites lower than 1000m asl, these are 500, 1000 and 1500 m asl., for the other sites they are station height and +- 500 m, except for Earlinet stations where all trajectories are calculated for 1500, 3000 and 5000 m arrival height.


Any comments, ideas, suggestions etc., are greatly welcome, e-mail to: Trajectories(at)nilu.no
Air mass trajectories are calculated using the Flextra model developed by Andreas Stohl (NILU) in cooperation with Gerhard Wotawa og Petra Seibert (Institute of Meteorology and Geophysics, Wienna) and using meteorological data provided from ECMWF (European Centre for Medium Range Weather Forcast). Publications using FLEXTRA results are requested to include an acknowledgement of, and citation to ECMWF, NILU and the model developers.
