Welcome to pyatmos’s documentation for Master!

The pyatmos software is a atmospheric properties library that produces reasonable atmospheric properties up to 500,000 feet. This goes far beyond the 1976 standard atmosphere’s limit of ~80,000 feet and is suitable for reentery problems.

Additionally, mixed units are supported.

Altitudes may be input in:
  • m, meters
  • ft, feet
  • kft, kilofeet
Velocities are in units of:
  • m/s
  • feet/s
  • knots
Densities are in units of:
  • kg/m^3
  • slug/ft^3
  • slinch/in^3
The following properties may be calculated:
  • pressure
  • temperature
  • density
  • dynamic pressure
  • speed of sound
  • equivalent airspeed
  • Reynolds number/unit length
  • dynamic viscosity
  • kinematic viscosity

Additionally, there is some support for vectorization with numpy.
