Estimation of the share of artificial Po-210 contamination in the ambient air [PDF]
Archives of Environmental Protection, 2021 In this work, source apportionment for unsupported 210Po was conducted. The activity size distributions of both supported and unsupported 210Po in urban aerosols were measured from February to December 2019.

Are contributions of emissions to ozone a matter of scale? [PDF]
Geoscientific Model Development, 2020 Anthropogenic and natural emissions influence the tropospheric ozone budget, thereby affecting air quality and climate. To study the influence of different emission sources on the ozone budget, often source apportionment studies with a tagged tracer ...

Source apportionment with one source unknown
Chemometrics and Intelligent Laboratory Systems, 1991 Abstract Attribution of local pollution to area sources is essential to effective management of the environment. Source apportionment addresses the problem by statistical inference of source contributions to total pollution from observations of ambient air chemical composition.

Quantifying black carbon light absorption enhancement with a novel statistical approach [PDF]
Atmospheric Chemistry and Physics, 2018 Black carbon (BC) particles in the atmosphere can absorb more light when coated by non-absorbing or weakly absorbing materials during atmospheric aging, due to the lensing effect.
