TL;DR: In this article, surface ozone has been measured over New Delhi, an urban site, a region of intensive anthropogenic activity since 1997, and the hourly averaged surface ozone data illustrates that on a large number of days the surface ozone values at Delhi exceed the World Health Organization (WHO) ambient air quality standards (hourly average of 80 ppb) for ozone.

TL;DR: In this article, the authors used day-side Measurement of Pollution in the Troposphere (MOPITT) carbon monoxide retrievals (2000-2007) to examine the regional CO emission and its transport pathways during the summer/winter monsoon, with a specific focus on the Indian-subcontinent.

TL;DR: In this paper, an analysis of tropospheric column ozone using the NASA Langley TOR data during 1979-2005 has been done to investigate the trend over major Indian cities Delhi, Hyderabad and Bangalore.

TL;DR: In this article, the spatial-temporal structure of total ozone column (TOC) over Portugal was analyzed for three scales: long-term, seasonal and short-term.

TL;DR: In this article, the authors analyzed the tropospheric ozone variability over the Iberian Peninsula (IP), NASA Langley TOR data have been analyzed for the 1979-2005 period.
