The phrase "ambient ground level" is correct and usable in written English.
It can be used in contexts related to environmental science, architecture, or audio engineering, referring to the baseline level of a particular measurement in a given environment.
Example: "The ambient ground level of noise in the city was significantly higher than in the countryside."
Alternatives: "background ground level" or "surrounding ground level".
The chemical composition of ambient ground-level fine particulate mass is of relevance for epidemiological and health impact studies.
A very easy implementation of this method, using ambient vibration measurements both at ground level and within buildings, is illustrated with an example application for the city of Beirut Lebanonn).
During the cooler months of May though August, the species selects tree holes closer to ground level, where ambient temperatures remain more stable.
For each collected ant, day time and ambient temperature (0.01°C resolution) at the ground level beside the collecting point were precisely determined via the use of temperature Dataloggers (Tinytag, Gemini Data Loggers).
We affixed the MP sampler to a tripod for ambient monitoring, approximately 1 m above ground level.
An interaction between air pollution and pollen loads is expected, e.g. thunderstorms, extreme precipitation events, increased ground level ozone concentrations, increased ambient air pollution from natural and anthropogenic sources and probably an increasing number of fires (19).
Von Ehrenstein et al. (2014) considered the risk of autistic disorder related to ground level measured exposure to monitored ambient air toxics from urban emissions during the pregnancy period [ 21].
The measurements of ambient temperature, pressure, wind speed and direction were made at 5 m above ground level and the cloud amount was observed visually every hour.
Ambient air was pumped into the containers and blown into the nutrient solution at ground level, aerating and blowing out the CO2 of the nutrient solution.
When a fire occurs in a room at ground level or a compartment located in the higher floors of a very tall building, the strong ambient wind will play an important role in fire spreading and smoke movement behavior.
