atmospheric pressure

“Japan is visited by the north and the west wind, the atmospheric pressure being lower on the Pacific Ocean than on the continent.”

The Catholic Encyclopedia, Volume 8: Infamy-Lapparent

“An altimeter which depends on measuring atmospheric pressure won't work at very low air pressures," Tom replied.”

“To stay conscious in the low atmospheric pressure of these extreme heights, the crew would have needed pressurized pure oxygen in their lungs and the PEAPs only supplied sea levelair, a mixture of about 80 percent nitrogen and 20 percent oxygen.”

“Whether death would come from the toxic corrosive crimson clouds, the sudden atmospheric pressure waves of 1200-degrees-Celsius heat, or the wildly fluctuating gravity fields that were a byproduct of the subspace inversion at the moon’s core no one could predict.”

Simon & Schuster: MILLENNIUM

“A standard altimeter could not tell the astronauts when they reached their perilune because an altimeter was an instrument that determined altitude based on changes in atmospheric pressure and the Moon has no atmosphere.”

Simon & Schuster: First Man

“When his near-vertical climb reached 90,000 feet, atmospheric pressure fell to a scant 6 millibars, about 1 percent of the pressure at sea level.”

“Deck, within which atmospheric pressure and normal temperature had been maintained for the benefit of the so-called "live" subjects — ranging from field mice down through brine shrimp, fruit flies and flatworms, to simple molds and spores.”
