Etymology

From atmosphere.

Noun

atmo (plural atmos)

1. (physics, dated) The standard atmospheric pressure used in certain physical measurements and calculations; conventionally, that pressure under which the barometer stands at 760 millimeters, at a temperature of 0° Centigrade, at the level of the sea, and in the latitude of Paris.
   • 1880? William Thomson, 1st Baron Kelvin, Heat

     under a constant pressure of one atmo

   • 1891, John Parker, Elementary Thermodynamics, page 309:

     In this case, at a pressure of one atmo, the quantity of gas absorbed by one gramme of water is .875 gramme at 0°C.

   • 1897 February, William Sutherland, “Two New Pressure-Gauges for the Highest Vacua”, in Philosophical Magazine, volume 43, number 261, page 88:

     Now the above change of ratio is established at a pressure about 2.5/10⁶ atmo as given by log. dec., when the mean free path of a molecule of air ought to be about 10⁶ × .00001 ÷ 2.5 centim. or 4 centim., which is about the radius of the bulb.

2. (science fiction) atmosphere (of a planet) (Can we verify⁽⁺⁾ this sense?)
