The phrase "atmospheric content" is correct and usable in written English.
It can be used in contexts related to environmental science, meteorology, or discussions about the composition of the atmosphere.
Example: "The atmospheric content of carbon dioxide has been steadily increasing over the past century, contributing to climate change."
Alternatives: "atmospheric composition" or "airborne constituents".
While emissions have flattened during the last several years globally, because about 44% of any and all emissions remain in the atmosphere, the atmospheric content of carbon dioxide is still growing and that is what really matters to climate change.
Both reflected sunlight on a planet and absorbed sunlight filtered through an atmosphere are two techniques humanity is presently developing to measure the atmospheric content and surface properties of distant worlds.
Concern over planned emissions of krypton-85 that might increase the atmospheric content of this gas by 15% a year led to a commissioning delay in October 1992.
"It now seems a much more formidable task, requiring global cooperation with swift recognition and response". One reason for special concern is the link between temperature and the atmospheric content of the so-called greenhouse gases.
It was the so-called Great Oxidation Event, two billion years after the formation of the planet, that drove Earth's atmospheric content of oxygen up by a factor of 10,000.
Science can say that if we burn another half-trillion tons of carbon the atmospheric content of carbon dioxide will go up by another 100 ppm and that will almost certainly lead to a warming of the planet greater than 2C, with major disruption of the climate system and huge risks for the natural world and human wellbeing.
The planet orbits its parent star every three and a half days, and each time it passes in front of its parent star, the atmospheric contents can be analyzed by examining how the atmosphere absorbs light passing from the star directly through the atmosphere in the direction of Earth.
Our proposed mechanism explains differences in the atmospheric contents of argon, krypton and xenon on Venus and Earth, but most of the neon must have escaped from both planets' atmospheres later to yield the observed ratio of neon to argon.
Because TESS is optimized to scour the stars nearest to us, it's greatest finds will be among the first targets for future, more powerful observatories that can not only detect these worlds, but measure their atmospheric contents.
By studying the atmospheric contents of ancient and present-day Earth, scientists say they've discovered specific chemical combinations that could reveal the presence of biological activity on other planets.
This is about 16 times that in the terrestrial biosphere and 60 times that in the preindustrial atmosphere, i.e., at a time before atmospheric CO2 content was altered by the increased burning of fossil fuels from human activities (Post et al. [1990]).
