Unprecedented Arctic ozone loss in 2011
Chemical ozone destruction occurs over both polar regions in local winter–spring. In the Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an ozone hole everyExpand

Arctic Ozone Loss and Climate Change
[1] We report the first empirical quantification of the relation between winter-spring loss of Arctic ozone and changes in stratospheric climate. Our observations show that ∼15 DU additional loss ofExpand

Preventing the loss of competence for neural induction: HGF/SF, L5 and Sox-2.
The response to neural induction depends on the presence of inducing signals and on the state of competence of the responding tissue. The epiblast of the chick embryo loses its ability to respond toExpand

cSox3 expression and neurogenesis in the epibranchial placodes.
Epibranchial placodes are local thickenings of the surface ectoderm, which give rise to sensory neurons of the distal cranial ganglia. The development of these placodes has remained unclear due toExpand

On the unexplained stratospheric ozone losses during cold Arctic Januaries
Using a combination of data from Match, POAM II, POAM III and MLS we show that the chemical loss rate of Arctic O3 during January of four cold winters (1992, 1995, 1996, and 2000) is consistentlyExpand

A tropical West Pacific OH minimum and implications for stratospheric composition
Most of the short-lived biogenic and anthropogenic chemical species that are emitted into the atmosphere break down efficiently by reaction with OH and do not reach the stratosphere. Here we show theExpand

Arctic Ozone Loss and Climate Sensitivity: Updated Three-Dimensional Model Study
[1] We have used a three-dimensional (3D) chemical transport model (CTM) to investigate the variation in Arctic winter-spring chemical ozone loss from 1991–2003, and its observed correlation with lowExpand

Ozone loss rates in the Arctic stratosphere in the winter 1994/1995 : Model simulations underestimate results of the Match analysis
We present box model simulations of ozone loss rates in the Arctic lower stratosphere for the winter 1994/1995. The ozone loss was simulated along each of the trajectories of the Match data set forExpand

Arctic winter 2005: Implications for stratospheric ozone loss and climate change
[1] The Arctic polar vortex exhibited widespread regions of low temperatures during the winter of 2005, resulting in significant ozone depletion by chlorine and bromine species. We show that chemicalExpand

Extrapolating future Arctic ozone losses
Future increases in the concentration of green- house gases and water vapour may cool the stratosphere fur- ther and increase the amount of polar stratospheric clouds (PSCs). Future Arctic PSC areasExpand
