AIRS Level 3 daily average water vapor from November 2018 to November 2019. Ascending and Descending orbits are plotted sequentially. The water vapor is plotted as an isosurface for a Mass Mixing Ratio of 1 g/kg. 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 that are dryer in yellow and regions that are wetter in blue. From the visualization we can see water vapor transport, higher concentrations that persist in the tropics, and the drying of the polar regions with the seasons.
