Journal ArticleDOI
Trends in solar spectral irradiance variability in the visible and infrared
TL;DR: In this article, the spectral irradiance (SSI) variability from 200 to 2400 nm was measured on the SORCE satellite, accounting for about 97% of the total solar irradiance.
Journal ArticleDOI
Solar Irradiance Reference Spectra (SIRS) for the 2008 Whole Heliosphere Interval (WHI)
Thomas N. Woods,Phillip C. Chamberlin,Jerald W. Harder,Rachel Hock,Martin Snow,Francis G. Eparvier,Juan Fontenla,William E. McClintock,Erik Richard +8 more
TL;DR: The IHY2007 Whole Heliosphere Interval (WHI) for solar Carrington Rotation 2068 (20 March to 16 April 2008) has been very successful in obtaining a wide variety of solar, heliospheric, and planetary observations during times of solar cycle minimum conditions as discussed by the authors.
Journal ArticleDOI
Mixing and ozone loss in the 1999–2000 Arctic vortex: Simulations with the three-dimensional Chemical Lagrangian Model of the Stratosphere (CLaMS)
Paul Konopka,H. M. Steinhorst,Jens-Uwe Grooß,Gebhard Günther,Rolf Müller,James W. Elkins,H. Jost,Erik Richard,Ulrich Schmidt,Geoffrey C. Toon,Daniel S. McKenna +10 more
TL;DR: In this paper, a 3D formulation of the Chemical Lagrangian Model of the Stratosphere (CLaMS-3d) is presented that extends the isentropic version of CLaMS to cross-isentropical transport.
Journal ArticleDOI

TL;DR: In this article, the authors used three fundamentally different approaches to derive the degree of chemical ozone loss from ozonesonde, balloon, aircraft, and satellite instruments and showed that the ozone losses derived from these different instruments and approaches agree very well, resulting in a high level of confidence in the results.
Journal ArticleDOI
In‐situ observations of mid‐latitude forest fire plumes deep in the stratosphere
H. Jost,K. Drdla,Andreas Stohl,Andreas Stohl,Leonhard Pfister,Max Loewenstein,Jimena P. Lopez,P. K. Hudson,P. K. Hudson,D. M. Murphy,Daniel J. Cziczo,Daniel J. Cziczo,Michael D. Fromm,T. Paul Bui,J. Dean-Day,Christoph Gerbig,Michael J. Mahoney,Erik Richard,Erik Richard,N. Spichtinger,Jasna V. Pittman,Elliot M. Weinstock,James C. Wilson,I. Xueref +23 more
TL;DR: The authors observed a plume of air highly enriched in carbon monoxide and particles in the stratosphere at altitudes up to 15.8 km, which can be unambiguously attributed to North American forest fires.
