The phrase "air broadening" is correct and usable in written English.
It is typically used in the context of physics or spectroscopy to describe the phenomenon where the spectral lines of an atom or molecule become wider due to interactions with surrounding air molecules.
Example: "The measurements showed significant air broadening, affecting the accuracy of the spectral analysis."
Alternatives: "pressure broadening" or "collisional broadening".
She has the hundred-and-eighty-degree extension that ballerinas, worldwide, now cultivate, but she uses it for dance purposes — to carve the air, broaden the arc — rather than for the merely visual purpose, so strange and fundamentally vulgar, of raising the foot to the ear.
The databank contains the line parameters (positions, intensities, self- and air-broadening coefficients, exponents of the temperature dependence of self- and air-broadening coefficients) of the principal isotopologue of NO2.
In addition to reference linestrengths S 296 K), the air-broadening coefficients γair(296 K) and temperature exponents n were inferred for strong transitions in five narrow regions, near 7185.60, 7203.89, 7405.11, 7426.14 and 7435.62 cm−1 that had been targeted as attractive for future diagnostics applications.
America is helping by providing intelligence and broadening the air corridor used by Turkish fighter jets.
However the Pentagon and the president's national security team are considering broadening the air campaign that has so far targeted Isis in Iraq into neighbouring Syria, as part of a concerted, internationally-backed effort to "degrade and destroy" the group.
In this his approach is like that of a physicist developing a physical theory for the highly artificial situation of a billiard table or air track and then broadening the theory to deal with a wider range of cases.
PARIS — Air travel disruptions intensified across Europe on Wednesday as a strike led by French air traffic controllers broadened in its second day to include smaller labor actions in other countries.
The crucial question is whether that air campaign is broadened to take in Isis strongholds in northern Syria.
After initially specialising in the movement of air, Dyson has broadened its technology into robotics, electric motors and 360-degree cameras.
