| Mace Head Back trajectories |
| Ensemble Backtrajectories calculated for Mace Head (250,1500 and 4000m above sea level) with Hysplit model. |
| At 05:00(UTC), the trajectory for the current day and the following are calculated with the latest GFS forecast available. The calculations are run on C-CAPS server. The trajectory ensemble consist of multiple trajectories calculated for the same location. Each member of the trajectory ensemble is calculated by offsetting the meteorological data by a fixed grid factor (one grid meteorological grid point in the horizontal and 0.01 sigma units in the vertical). This results in 27 members for all-possible offsets in X,Y, and Z.(More info) |
