Complete 1976 Standard Atmosphere Model

This is a complete model of the 1976 US standard atmosphere model with valid data between sea level and 1000 km. This set of functions returns Temperature, Pressure, Density, Speed of Sound, Gravity, Dynamic and Kinematic Viscosity, Coefficient of Thermal Conductivity, Gas Number Density at desired altitudes. Ability to convert to English Units as desired.

Values DO differ by less than 1% due to different integration technique and should be closer to the actual values of the integrals described in the 1976 U.S. Standard Atmosphere
