The phrase "atmosphere below" is correct and usable in written English.
It can be used when referring to the atmospheric conditions or layers that exist beneath a certain point, such as in a scientific or descriptive context.
Example: "The temperature in the atmosphere below the cloud layer was significantly warmer than above."
Alternatives: "lower atmosphere" or "subsurface atmosphere".
Scrubbing of the atmosphere below cloud level is one factor that could contribute to the presence of microorganisms in precipitation.
In particular, cloud emission must be transmitted through the atmosphere below the cloud to reach the surface and have an impact.
This approach would keep concentrations of carbon dioxide in the atmosphere below 500 parts per million, a level thought to avoid the worst impacts of climate change.
We present Monte Carlo simulations of the energy deposited by energetic electrons from the outer Van Allen belt precipitating into the atmosphere below 100 km.
It allows to investigate the Martian atmosphere below 55 km by retrieving the temperature profiles from the 15 μm CO2 band.
He added: "We will be damned lucky, given what things look like at the moment, if we manage to keep the atmosphere below 500 parts per million and most scientists would translate that to be probably in the region of 3C".
About the chill in the intellectual climate, Mr. Berman writes: "Two developments account for it — two large new realities that, condensing overhead, have altered the intellectual atmosphere down below, almost without being noticed.
Atmosphere n.1, below, shows a changing panoramic sky.
Argon and combined argon and reactive gas atmospheres at below 0.5 Pa were used.
After sunrise, heating of the surface gradually erodes the stable atmosphere from below until the unstable daytime profile is reestablished.
While in Castmatic the pressurized argon shielded arc melting is followed by gravity casting that is accelerated by two atmospheres argon pressure above and one atmosphere vacuum below.
