The measurement of this quantity by radiosonde uses an aneroid cell, which is made of a beryllium-copper alloy, has had part of its air evacuated, and is attached to a stiff spring.

A geopotential height is indexed to a constant value for this quantity. The force due to this quantity's gradient is balanced by the Coriolis force for geostrophic winds. The eye of a cyclone has a much (*) lower value for this quantity relative to outside of the cyclone and is thus depicted on a weather map with a red L. This quantity is commonly measured in inches of mercury of millibars, and it is measured with a barometer. For 10 points, identify this force that the weight of the atmosphere exerts on objects.
