Transport in the Middle Atmosphere (2007, background): “Studies of transport properties in CTMs driven by analyses have indeed suggested that transport is much too dispersive, and age of air therefore much too young at middle and high latitudes (Schoeberl et al. 2003).”
Tropical troposphere‐to‐stratosphere transport inferred from trajectory calculations (2004, background): “[19] Schoeberl et al.[2003] and W. Tan et al. (A case study ofexcessivesubtropicaltransport in the stratosphere of a data assimilation system, submitted to Journal of Geophysical Research, 2003) report on problems of overestimation of tropical/extratropical exchange at the tropopause level of anal”
New version of the TOMCAT/SLIMCAT off‐line chemical transport model: Intercomparison of stratospheric tracer experiments (2006, methodology): “Schoeberl et al. (2003) compared age of air simulations using a trajectory model and a 3D CTM forced by both analyses and GCM winds.”
Impact of the vertical velocity scheme on modeling transport in the tropical tropopause layer (2010, background): “In the theory of age spectra [Hall and Plumb, 1994; Waugh and Hall, 2002; Schoeberl et al., 2003], the term age corresponds to the transit time of an air parcel between two locations and age spectrum to the distribution of these ages within a given volume of air.”
Goddard Earth Observing System chemistry‐climate model simulations of stratospheric ozone‐temperature coupling between 1950 and 2005 (2008, methodology): “Use of the Lin [2004] dynamical core in the GEOS CCM is one of the main factors that lead to successful transport characteristics, evidenced by the ‘‘tape recorder’’ signal and the age-of-air distribution in the work of Eyring et al. [2006], and by realistic particle dispersion characteristics [ Sch”
