The phrase "atmosphere concentration" is correct and usable in written English.
It can be used in scientific contexts, particularly when discussing the amount of a substance present in the atmosphere.
Example: "The atmosphere concentration of carbon dioxide has been steadily increasing over the past century."
Alternatives: "atmospheric concentration" or "concentration in the atmosphere".
He wants to create trees that would store more carbon in their root systems -- "sequestering" it from the atmosphere, thereby cutting atmospheric concentrations of carbon dioxide, the heat-trapping greenhouse gas.
This is because, unlike stable isotopes or chloride, they undergo a process of equilibration with the atmosphere, and historical atmospheric concentrations are known.
In the Mars atmosphere the concentration of oxygen is not high enough to decrease the concentration of metal ions through this reaction.
Drawing safety lines in the atmosphere's concentration of greenhouse gases is all about how much risk you are prepared to tolerate.
Without prompt action, the atmosphere's concentration of greenhouse gases, mainly carbon dioxide from burning fossil fuels, is expected to double from pre-industrial levels by the end of this century, the scientists said.
Influencing factors were investigated systematically including the relative humidity of atmosphere, the concentration of polymer solutions and the temperature.
But Occam's razor argues persuasively for the simpler explanation: Since the Industrial Revolution, we have increased the atmosphere's concentration of carbon dioxide — known to trap heat — by an incredible 40percentt.
Experiments were conducted in a constant-volume combustion vessel under varying conditions with respect to atmosphere, oxygen concentration, injection pressure, ambient temperature, and nozzle-hole diameter.
Since the main sources of nitrate in the environment are generally from the surface and/or atmosphere, the concentration of NO3 is generally high in the shallow wells.
