Surface pressure

From Wikipedia, the free encyclopedia

Surface pressure is the atmospheric pressure at a point of Earth's surface. It is directly proportional to the mass of air over that point.

For numerical reasons, atmospheric models such as general circulation models (GCMs) usually predict the nondimensional logarithm of surface pressure.

Surface pressure is also the area of water surface available to each molecule in a solution. The measurement of surface pressure is key in determining the monolayer properties of an amphiphilic material.
