  "**Not today's weather.** A storm or a heat wave moves the real pressure by a few per cent; a barometer reading beats the model.",
  "**Oxygen is the same share.** About 20.9% of the air at every height here; there is less of it because there is less air.",
  "**Boiling from the Antoine equation.** Water's vapour pressure fitted from 1 °C to above 100 °C.",
  "**The troposphere only.** Heights from −500 m to 11,000 m; above that the model changes and the card stops.",
  "**Not medical advice.** How a person feels at altitude varies; the card gives the air, not the body."
