 Context examples 

On the other hand, the atmospheric pressure of Mars is now less than 1% of Earth's, and the oceans and rivers that once dotted the Red Planet's surface have disappeared.

With Mars being further away from the Sun, researchers estimate a CO2 pressure similar to Earth’s total atmospheric pressure is needed to raise temperatures enough to allow for stable liquid water.

A unit of temperature of the temperature scale designed so that the freezing point of water is 0 degrees and the boiling point is 100 degrees at standard atmospheric pressure.

(Degree Celsius, NCI Thesaurus)

Oxygen that is at an atmospheric pressure higher than the pressure at sea level.

By performing liquid-phase exfoliation of graphite – a process that creates graphene – in the presence of titania nanoparticles, using only water and atmospheric pressure, the scientists created the new graphene-titania nanocomposite.

Though Io’s hyperactive volcanoes are the ultimate source of the SO2, sunlight controls the atmospheric pressure on a daily basis by controlling the temperature of the ice on the surface.

Although clouds might explain the opacity, they become less and less sustainable as the pressure decreases, and the opacity has been observed where the atmospheric pressure is very low.

When Mars formed 4.5 billion years ago, it had a much thicker atmosphere and higher atmospheric pressure.

(Heavy Rain May Have Once Fallen on Mars, VOA)

The moist air is typically applied at increased atmospheric pressure and the process is restricted to objects that can withstand high temperature and pressure.

(Moist Heat or Steam Sterilization, NCI Thesaurus)

Oxygen that is administered at a higher pressure compared to standard (i.e. sea-level) atmospheric pressure.
