Journal ArticleDOI
Assessing future nitrogen deposition and carbon cycle feedback using a multimodel approach: Analysis of nitrogen deposition
Jean-Francois Lamarque,Jeffrey T. Kiehl,Guy Brasseur,Tim Butler,Philip Cameron-Smith,W. Collins,William J. Collins,Claire Granier,Claire Granier,Didier Hauglustaine,Peter Hess,Elisabeth A. Holland,Larry W. Horowitz,Mark Lawrence,Daniel S. McKenna,P. Merilees,Michael J. Prather,P. J. Rasch,D. A. Rotman,Drew Shindell,Peter E. Thornton +20 more
TL;DR: In this article, the authors present the results of nitrogen deposition on land from a set of 29 simulations from six different tropospheric chemistry models pertaining to present-day and 2100 conditions, using the results from all models, they have documented the strong linear relationship between models on the fraction of the nitrogen emissions that is deposited, regardless of the emissions (present day or 2100).
Journal ArticleDOI

A. Rotman,Deianeira Z. Stockwell,Peter van Velthoven,Gé Verver,Oliver Wild,Hu Yang,Peter H. Zimmermann +29 more
TL;DR: In this article, simulations of 222Rn and other short-lived tracers are used to evaluate and intercompare the representations of convective and synoptic processes in 20 global atmospheric transport models.
Journal ArticleDOI
The chemical and radiative effects of the Mount Pinatubo eruption
TL;DR: In this paper, a two-dimensional (2-D) zonally averaged chemical radiative transport model was integrated with time from before the eruption through December 1993, and the modeled impact on global ozone results from increased rates of heterogeneous reactions on sulfate aerosols and from the increased radiative heating and scattering caused by these aerosols.
Journal ArticleDOI
IMPACT, the LLNL 3‐D global atmospheric chemical transport model for the combined troposphere and stratosphere: Model description and analysis of ozone and other trace gases
D. A. Rotman,C. S. Atherton,Dan Bergmann,Philip Cameron-Smith,Catherine C. Chuang,Peter S. Connell,Jane Dignon,A. Franz,K. E. Grant,Douglas E. Kinnison,Douglas E. Kinnison,C. R. Molenkamp,D. Proctor,J. R. Tannahill +13 more
TL;DR: The Integrated Massively Parallel Atmospheric Chemical Transport (IMPACT) model as discussed by the authors is a global chemical transport model that treats chemical and physical processes in the troposphere, the stratosphere, and the climatically critical tropopause region.
Journal ArticleDOI
Global Modeling Initiative assessment model: Model description, integration, and testing of the transport shell
D. A. Rotman,J. R. Tannahill,Douglas E. Kinnison,Douglas E. Kinnison,Peter S. Connell,Dan Bergmann,D. Proctor,Jose M. Rodriguez,Shian-Jiann Lin,Richard B. Rood,Michael J. Prather,P. J. Rasch,D. B. Considine,R. Ramaroson,Stephan R. Kawa +14 more
TL;DR: In this article, the authors describe the three-dimensional global stratospheric chemistry model developed under the NASA Global Modeling Initiative (GMI) to assess the possible environmental consequences from the emissions of a fleet of proposed high-speed civil transport aircraft.
