Factors affecting the detection of trends: Statistical considerations and applications to environmental data
Gregory C. Reinsel,George C. Tiao,Xiao-Li Meng,Dongseok Choi,Wai Kwong Cheang,Teddie L. Keller,John J. DeLuisi,Donald J. Wuebbles,James B. Kerr,Alvin J. Miller,Samuel J. Oltmans,John E. Frederick +11 more
TL;DR: In this article, the authors provided formulae for estimating the number of years necessary to detect trends, along with the estimates of the impact of interventions on trend detection, and the uncertainty associated with these estimates is also explored.
Journal ArticleDOI
The Indian Ocean Experiment: Widespread Air Pollution from South and Southeast Asia
Jos Lelieveld,Paul J. Crutzen,Veerabhadran Ramanathan,Meinrat O. Andreae,Carl A. M. Brenninkmeijer,Teresa Campos,Glen R. Cass,Russell R. Dickerson,Horst Fischer,J. A. de Gouw,Armin Hansel,Anne Jefferson,Dieter Kley,A. T. J. de Laat,Shiv Lal,Mark Lawrence,Jürgen M. Lobert,Olga L. Mayol-Bracero,Abhijit Mitra,T. Novakov,Samuel J. Oltmans,Kimberly A. Prather,Thomas Reiner,Henning Rodhe,H. A. Scheeren,D. Sikka,Jonathan Williams +26 more
TL;DR: It is shown that agricultural burning and especially biofuel use enhance carbon monoxide concentrations and Fossil fuel combustion and biomass burning cause a high aerosol loading, which gives rise to extensive air quality degradation.
Journal ArticleDOI
Global Distribution and Trends of Tropospheric Ozone: An Observation-Based Review
Owen R. Cooper,David D. Parrish,Jerry Ziemke,Manuel Cupeiro,Ian E. Galbally,S. Gilge,Larry W. Horowitz,N. R. Jensen,Jean-Francois Lamarque,Vaishali Naik,Samuel J. Oltmans,James J. Schwab,Drew Shindell,Anne M. Thompson,Valérie Thouret,Yuxuan Wang,R. M. Zbinden +16 more
TL;DR: In this paper, an up-to-date overview of tropospheric ozone distribution and trends is presented, along with some new and extended analyses using well-known and referenced datasets to draw connections between ozone trends and distributions in different regions of the world.
Journal ArticleDOI
Southern Hemisphere Additional Ozonesondes (SHADOZ) 1998–2000 tropical ozone climatology 1. Comparison with Total Ozone Mapping Spectrometer (TOMS) and ground-based measurements
Anne M. Thompson,Jacquelyn C. Witte,Richard D. McPeters,Samuel J. Oltmans,Francis J. Schmidlin,Jennifer A. Logan,Masatomo Fujiwara,Volker W. J. H. Kirchhoff,Franc¸oise Posny,Gert J. R. Coetzee,Bruno Hoegger,Shuji Kawakami,Toshihiro Ogawa,Bryan J. Johnson,H. Vomel,Gordon Labow +15 more
TL;DR: The Southern Hemisphere Additional Ozonesondes (SHADOZ) project as mentioned in this paper collected ozone profiles from 10 southern hemisphere tropical and subtropical stations and compared column-integrated total ozone from sondes with the Earth-Probe/Total Ozone Mapping Spectrometer (TOMS) satellite and ground-based instruments.
Journal ArticleDOI
Arctic smoke – record high air pollution levels in the European Arctic due to agricultural fires in Eastern Europe in spring 2006
Andreas Stohl,Torunn Berg,Torunn Berg,John F. Burkhart,John F. Burkhart,A. M. Fjǽraa,Caroline Forster,Andreas Herber,Øystein Hov,Chris Rene Lunder,W. W. McMillan,Samuel J. Oltmans,Masataka Shiobara,David Simpson,Sverre Solberg,Kerstin Stebel,Johan Ström,Kjetil Tørseth,R. Treffeisen,K. Virkkunen,K. Virkkunen,Karl Espen Yttri +21 more
TL;DR: In this article, the authors used the FLEXPART particle dispersion model to show that smoke from agricultural fires in Eastern Europe intruded into the European Arctic and caused the most severe air pollution episodes ever recorded there.
