    • Atmospheric pressure, other reference values
  • A model of how atmospheric pressure varies with altitude:
    • The U.S. Standard Atmosphere, a series of models that give values for pressure, density, and temperature over a range of altitudes

Famous quotes containing the words standard and/or atmosphere:

    “We don’t want bores in the theatre. We don’t want standardised acting, standard actors with standard-shaped legs. Acting needs everybody, cripples, dwarfs and people with noses so long. Give us something that is different.”
    —Dame Sybil Thorndike (1882–1976)

    “A noble soul is not the one that can manage the highest flights but the one that rises very little and falls very little but always dwells in a free, resplendent atmosphere and altitude.”
