Plotting an atmospheric property.

This package provides support for plotting how US Standard Atmosphere properties vary with altitude.

This loads the package.
The speed of sound does not decrease monotonically with increasing altitude.
The speed of particles does not increase monotonically with increasing altitude.

Atmospheric properties.

You can also treat the various atmospheric properties as functions of altitude. These functions understand the units defined in the Units Package.

This gives the mean particle speed at 5 kilometers.
