Preface for the Polar Ozone Special Issue

Abstract

A total of 24 papers have been considered for inclusion in the special issue. These papers underwent the normal JGR reviewing process. With an impending polar mission to the Arctic in the fall of 1991, it was a Herculean effort for many of the authors and reviewers to participate in the preparation of this issue. We are therefore most grateful to our colleagues for their assistance. We trust that this issue will continue the "saga" of polar ozone depletion and will be but an intermediate step, as the scientific community unravels the complex and fascinating chemical, dynamical, and radiative processes at work in the polar stratosphere.

Scale invariance in jet streams: ER‐2 data around the lower‐stratospheric polar night vortex

“…Because K(1) = 0, the quantity H 1 is a good estimate of the scaling exponent in both monofractal and multifractal cases. All flight segments used were flown on an approximate great circle of 3000 s duration during: the Airborne Antarctic Ozone Experiment (AAOE, Tuck et al 1989); the Airborne Arctic Stratospheric Experiment (AASE, Cicerone et al 1992); the second Airborne Arctic Stratospheric Experiment (AASE II, Anderson and Toon 1993); the Airborne Southern Hemisphere Ozone Experiment (ASHOE, Tuck et al 1997b); and the SAGE 3 Ozone Loss and Validation Experiment (SOLVE, Newman et al 2002). The AASE and SOLVE missions had, respectively, four and five such flight segments in the along-jet direction; the remaining 66 Arctic legs were in the across-jet direction.…”
