The phrase "atmospheric increase" is correct and usable in written English.
It can be used in contexts discussing changes in atmospheric conditions, such as climate change or pollution levels.
Example: "The atmospheric increase of carbon dioxide is a significant factor contributing to global warming."
Alternatives: "rise in atmospheric levels" or "increase in atmospheric concentration".
"A substantial contribution of U.S. shale gas industry to the recent methane atmospheric increase seems unlikely," it concludes.
The atmospheric increase of CO2 (3 Gton yr−1) can be balanced by an engineered sink with an area of no more than 75,000 km2 at v of 1 cm s−1.
The airborne fraction of CO2 emission, defined as the observed atmospheric increase divided by emissions of fossil CO2, has been remarkably constant over the last 50 years [6].
Note that the increase in oceanic CO2 over the past 17 years is consistent with the atmospheric increase, within the statistical limits of the measurements (Doney et al. [2009]).
The other experiment, to be published in an upcoming issue of Global Change Biology, indicates that an atmospheric increase to 550 parts-per-million of CO2 would boost soy yields by about 15%, a third less benefit than seen in previous studies.
In 2007 climate scientists of the IPCC concluded that there was at least a 90% probability that atmospheric increase in CO2 was human-induced, mostly as a result of fossil fuel emissions but, to a lesser extent from changes in land use.
Atmospheric stability increase was associated with concentration increase.
This study has shown that density and aromaticity of atmospheric residuum increases simultaneously with increase in asphaltenes.
We also found that the count-rate increases as the atmospheric pressure increases.
Harvey, L. D. D. Mitigating the atmospheric CO2 increase and ocean acidification by adding limestone powder to upwelling regions.
Within the next century temperature and atmospheric CO2 increase will significantly affect this ecosystem type.
