The phrase "ambient population" is correct and usable in written English.
It can be used in contexts related to ecology, sociology, or urban studies to refer to the general population present in a specific area or environment.
Example: "The ambient population of the city has increased significantly over the past decade, leading to various social and environmental challenges."
Alternatives: "surrounding population" or "local population".
The data used here are a proxy for the ambient population.
This paper attempts to address this, and produce an examination of the ambient population.
Malleson and Andresen Examines risk of crime taking into account ambient population and hour of day.
Hence it becomes apparent that a lack of data is the main barrier to further research into the ambient population.
The ambient population is highly dynamic and exhibits strong spatial and temporal fluctuations at various scales (e.g. hourly, daily, seasonal).
He separated population into nighttime (residential) population, daytime residential population, daytime worker and student population, and ambient population.
We multiplied the fraction of residential PPM2.5 attributable to household cooking by the proportion of total ambient population-weighted PM2.5 attributable to household combustion (PM2.5-hh) (Equation 2).
Our objective was to systematically estimate the contribution of household air pollution from cooking with solid fuels (PM2.5-cook) to outdoor ambient population-weighted PM2.5 air pollution (APM2.5), by region, in 1990, 2005, and 2010.
We used global estimates of annual average ambient population-weighted PM2.5 concentrations, which were developed for the GBD 2010 study (Brauer et al. 2012) as well as the Global Energy Assessment (Riahi et al. 2012), to estimate the proportions and absolute concentrations of PM2.5-cook, on a regional basis.
Our results also indicate that none of the three albumin adducts would be useful biomarkers of benzene exposure in ambient populations, where air concentrations rarely exceed 0.1 ppm, or in working populations where exposures are consistently maintained at < 1 ppm.
Threshold limit values are an approach to assessing health effects for occupational chemical exposures that are generally much higher (often orders of magnitude higher) than levels considered acceptable for ambient or population-level exposures.
