The phrase "ambient ground" is correct and usable in written English.
It can be used in contexts related to environmental design, soundscapes, or discussions about the surrounding atmosphere or background elements.
Example: "The ambient ground of the café created a relaxing atmosphere, perfect for reading or working."
Alternatives: "surrounding environment" or "background setting".
The chemical composition of ambient ground-level fine particulate mass is of relevance for epidemiological and health impact studies.
Figure 9 shows the profile of the ambient air, ground surface and below the ground for depths of 0.5, 1, 5, 10, 15, 20, 25 and 30 m.
A promising approach to condition those buildings in summer employs the utilization of the building's thermal storage activated by natural heat sinks (e.g., ambient air, ground water or soil) through night ventilation or thermally activated building systems (TABS).
You don't need special geological hotspots, because the ambient UK ground temperature, of 10-14C, is fully capable of permitting space heating and cooling using an elegant device called a heat pump, which lifts the temperature of the heat being extracted, and consumes only a quarter of the energy that it provides as useful heat.
It is demonstrated that despite the cyclic nature of the daily and seasonal variations of the ambient and ground surface temperatures, the underground temperature variations diminish with depth and stabilize throughout the year at around 21 °C starting from a depth of 5 m below the surface.
Residential heat exchangers use the heat difference between ambient and ground (or air) temperatures.
The collected samples were dried at ambient temperature, ground and sieved with a <2 mm mesh and kept in polyethylene packages till analysis.
Six variables influencing the thermal performance of the earth-to-air heat exchangers which were taken into account are length, humidity, ambient air temperature, ground surface temperature, ground temperature at burial depth and air mass flow rate.
