j@1040: Arctic ozone loss calculations j@1040: ============================== j@1040: j@1040: Here we show the temporal development of Arctic ozone depletion averaged j@1040: over the polar vortex on the basis of simulations of j@1040: `Chemical Lagrangian Model of the Stratosphere (CLaMS)`_ for different j@1040: years. j@1040: j@1040: The upper panel shows the temporal development of simulated ozone depletion j@1040: as a function of height and the lower panel shows the column ozone loss between 12 and j@1040: 22 km in Dobson units (DU). For comparison, the maximum ozone losses for j@1040: the other years are shown as colored arrows on the right side of the figure. j@1040: The CLaMS simulation ends with the collapse of the polar vortex, j@1040: after the air is mixed with ozone-rich air from lower latitudes. j@1040: j@1040: j@1040: .. _Chemical Lagrangian Model of the Stratosphere (CLaMS): http://en.wikipedia.org/wiki/CLaMS
