Standard atmosphere, unit of pressure, equal to the mean atmospheric pressure at sea level. It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere, which is also referred to as one atmosphere, is equivalent to.

The standard atmosphere (symbol: atm) is a unit of pressure defined as 101 325 Pa. It is sometimes used as a reference pressure or standard pressure . It is approximately equal to Earth 's average atmospheric pressure at sea level .
Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface and is a function of the mass of the planet, the radius of the surface, and the amount and composition of the gases and their vertical distribution in the atmosphere.
The United Nations Environment Programme (UNEP) convened a multidisciplinary expert panel to undertake a rapid review of the state of scientific research on Solar Radiation Modification (SRM)
19 de oct. de 2023 · An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
Atmospheric pressure is the force per unit area exerted by a body of air above a specified area (called an atmospheric column). It is expressed in several different systems of units, including millimeters (or inches) of mercury, pounds per square inch (psi), millibars (mb), or standard atmospheres.
