The phrase "air composition" is correct and can be used in written English.
You could use it to describe the composition of the air in a particular environment, e.g. "The air composition in this part of the forest is unusually high in carbon dioxide."
The surface of the Earth, meanwhile, is uninhabitable, as the air composition has been changed so as to make it unbreathable.
Galvanostatic charge and discharge simulations show that air composition strongly impacts zinc air battery operation.
Fire detection was facilitated with the use of three low-cost air composition sensors fed into an artificial neural network.
Lots of previous work had been done, but mostly as an offshoot of other studies, like biologists wanting a baseline for looking at the air composition in some kind of respiratory chamber.
On the basis of preliminary investigations, the sub-optimal package air composition of 5% O2 and 5% CO2 in N2 was appropriate for designing the optimal MA packages.
Processes which produce slow changes in air composition in a closed ecological system (CES) may not be noticed if the leak rate of the CES is significant.
The droplet autoignition behaviour has been analysed in both physical and mixture fraction space for a wide range of vitiated air compositions and initial droplet diameters.
The relationship between odor concentrations (olfactometry) and chemical concentrations (gas chromatography-mass spectrometry, GC-MS) was studied for the odorous air compositions of a rendering plant, a sanitary landfill and an industrial area with large petroleum and petrochemical industries.
For gas species common in both volcanic gas and atmosphere such as CO2 and H2O, difference in ambient air compositions near the vent and at observation site causes over estimation of volcanic gas ratios at one time but does under estimation at other times.
Water level at anode and cathode, species concentrations and cell potential are shown to vary with air-composition impact during operation and may reach critical values which reduce battery lifetime.
The effect of the silane - air mixture composition on the ignition limits was found.
