AIRS Level 3 daily average ozone from August 2019 to November 2019. Ascending and Descending orbits are plotted sequentially. The ozone is plotted as an isosurface for a volume mixing ratio of 5e-7 (unitless). The height and scale of the isosurface are enhanced to highlight the variability. The isosurface height is colored from yellow to blue. This has the effect of highlighting regions with higher ozone in yellow and regions with lower ozone in blue. From the visualization we can see the Antarctic polar vortex and the formation of the ozone hole in late September. The isosurface becomes fully transparent when it reaches an altitude of 18 km to enhance the visibility of the ozone hole.
