Unlike other similar visualizations that show just surface data, I like that you can QUICKLY look at weather data at various altitudes. For example, click on the temperature icon on the left side of the display, then click on the altitude icon just below. 700mb generally corresponds to 9,500ft - 10,000ft. 500mb generally corresponds to 16,500ft to 17,500ft.
It wouldn't be difficult to write software that generates skew-t soundings at each grid point but you'd need access to the gridded data.
