The phrase "a low ambient" is correct and usable in written English.
It can be used in contexts discussing environmental conditions, particularly in relation to sound, light, or temperature levels.
Example: "The room was designed to create a calming atmosphere with a low ambient light that was easy on the eyes."
Alternatives: "a low background" or "a subdued environment".
In addition, environmental analysis shows the system can be more beneficial for the environment with a low ambient temperature.
The largest effect on the methane potential was registered from tests performed at high altitudes due to a low ambient pressure.
The trapping efficiency of the device for nano-particles above 2 nm in size is more than 99.8% at a low ambient pressure below about 160 Pa.
The probability of nano-particles above 2 nm in size to a stainless-steel wall is close to 100% at a low ambient pressure below about 160 Pa.
The measured results of the prototype demonstrate that it can provide a high temperature and high-capacity water supply even under a low ambient temperature of −10∼−15 °C.
It is pointed out that for partially cloudy conditions with a low ambient temperature and high wind speeds, the thermal efficiency of the solar disinfectant is at a minimum.
In addition, the low specific activity of the pure rock salt and a low concentration of radon lead to an extremely low ambient dose equivalent rate of less than 1 nSv/h.
These comparisons were conducted on a subsample of five runners on two study days, one chosen to represent a day with high ambient sulfate levels and the other a day with low ambient sulfate levels.
The 4-AFC test was performed in a darkened room with a constant level of low ambient lighting and images were presented on a DICOM-calibrated megapixel colour LCD screen (Radiforce RX320 LCD, EIZO Corporation) with a native resolution of 1536 × 2048.
The injection mass flow rate in a vapor injection CO2 cycle is an important design factor to improve the heating performance of a heat pump at low ambient temperatures.
In addition, we recruited a control group (Stanford cohort) which consisted of 40 subjects from Palo Alto, California, a region with relatively low ambient air pollution (California Air Resources Board (CARB), http://www.arb.ca.gov).
