Trajectories over ice

Backward trajectories (arriving at Oden, total run time 10 hours) are plotted together with the arctic ice cover (threshold: 30% ice cover) for every day of Oden´s ice drift.

The trajectories were calculated for three different arrival heights (100m, 500m, 2000m), and can be found in separate zip-folders:

Trajectories_over_ice_100m.zip
Trajectories_over_ice_500m.zip
Trajectories_over_ice_2000m.zip

Each zip-folder contains one plot for every day (24h) of Oden´s ice drift with 4 backward trajectories, arriving every 6 hours (see below); on the trajectories a white dot marks every 24 hours.

Colour code for the trajectories:
black: arriving at Oden at 0 UTC
blue: arriving at Oden at 6 UTC
magenta: arriving at Oden at 12 UTC
green: arriving at Oden at 18 UTC

The plots are saved in three formats: png, _bw.eps (black and white), and _co.eps (coloured) with a filename according to the respective date and arrival height.
