Modeling reflectance and transmittance of quartz-fiber filter samples containing elemental carbon particles: Implications for thermal/optical analysis
TL;DR: A radiative transfer scheme that considers absorption, scattering, and distribution of light absorbing elemental carbon (EC) particles collected on a quartz-fiber filter was developed to explain simultaneous filter reflectance and transmittance observations prior to and during thermal/optical analysis for carbonaceous aerosol as discussed by the authors.

Comparison of PM2.5 carbon measurement methods in Hong Kong, China.
TL;DR: Hong Kong experienced OC levels similar to those at US sites, but has much higher EC concentrations, and OC/EC ratios range from 2 to 5 at two US sites and from 0.2 to 1.2 at three Hong Kong sites.

TL;DR: Li et al. as mentioned in this paper investigated carbonaceous pollution signatures in road dusts and urban soils and evaluated potential sources in Xi'an, China, finding that elemental carbon (EC) is not only a light absorbing constituent that warms the atmosphere but also a significant environmental pollutant.

TL;DR: In this article, twenty-one samples were collected during the dry season (26 January-28 February 2004) at 12 sites in and around Addis Ababa, Ethiopia and analyzed for particulate matter with aerodynamic diameter.

PM10 measurements at McMurdo Station, Antarctica
TL;DR: The average PM 10 aerosols at McMurdo Station, Antarctica were sampled continuously during the austral summers of 1995}1996 and 1996}1997 as discussed by the authors, and averaged 3.4 l gm ~3, more than an order of magnitude lower than the USEPA annual average National Ambient Air Quality Standard (NAAQS).
