+This package is an archive of scientific routines that implement the

+as exponential, coesa76, nrlmsise00, and jb2008. 
 
-The package mainly estimates density, temperature, pressure and other parameters 
-of air at a set of specific altitudes. For atmosphere below 86 kilometers, it also 
-calculates the speed of sound, viscosity, and thermal conductivity.
