TL;DR: For the 2008 Olympic and the Paralympic Games held in Beijing, China, strict controls on pollutant emissions and motor vehicle traffic were imposed on Beijing and neighboring provinces to the South to improve the air quality in and around the city as mentioned in this paper.

TL;DR: In this article, the air mass factors used to convert line-of-sight "slant" columns to vertical columns were re-calculated for this region based on updated and higher resolution input information including absorber profiles from a regional-scale (15 km × 15 km resolution) air quality model, higher spatial and temporal resolution surface reflectivity, and an improved treatment of snow.

TL;DR: In this article, an optical-photochemical coupled model incorporating water column optics and experimental measurements of photoproduction of dissolved inorganic carbon (DIC), the main carbon product of DOM photochemistry, was used to make the first quantitative estimates of photomineralization of tDOM in a coastal Arctic ecosystem under current and future sea ice regimes.

TL;DR: Scarn et al. as discussed by the authors proposed a joint center for Earth Systems Technology (NASA/UMBC), University of Maryland Baltimore County, 1000 Hilltop Circle, Baltimore, MD 21231, USA.

TL;DR: This study presents the first interannual comparison of SO2 emissions and the satellite SO2 observations from the Ozone Monitoring Instrument for Indian coal-fired power plants during the OMI era of 2005-2012, and suggests the air quality monitoring network needs to be optimized to reflect the true SO2 situation in India.
