Northern winter stratospheric temperature and ozone responses to ENSO inferred from an ensemble of Chemistry Climate Models
Northern winter stratospheric temperature ozone responses Chemistry Climate Models
2009/12/3
The connection between the El Niño Southern Oscillation (ENSO) and the Northern polar stratosphere has been established from observations and atmospheric modeling. Here a systematic inter-compa...
Comment on "Quantitative performance metrics for stratospheric-resolving chemistry-climate models" by Waugh and Eyring (2008)
Quantitative performance metrics stratospheric-resolving chemistry-climate models Waugh Eyring

This comment focuses on the statistical limitations of a model grading, as applied by D. Waugh and V. Eyring (2008) (WE08). The grade g is calculated for a specific diagnostic, which basically relates...
The simulation of the Antarctic ozone hole by chemistry-climate models
Antarctic ozone hole chemistry-climate models

While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used ...
Water vapour transport in the tropical tropopause region in coupled Chemistry-Climate Models and ERA-40 reanalysis data
Water vapour transport tropical tropopause region coupled Chemistry-Climate Models

In this study backward trajectories from the tropical lower stratosphere were calculated for the Northern Hemisphere (NH) winters 1995–1996, 1997–1998 (El Niño) and 1998–1999 (La Niña) a...
Clear sky UV simulations for the 21st century based on ozone and temperature projections from Chemistry-Climate Models
Clear sky UV 21st century ozone and temperature projections Chemistry-Climate Models
2009/3/13
We have estimated changes in surface solar ultraviolet (UV) radiation under cloud free conditions in the 21st century based on simulations of 11 coupled Chemistry-Climate Models (CCMs). The total ozon...
Uncertainties and assessments of chemistry-climate models of the stratosphere
chemistry-climate models stratosphere
2009/3/10
In recent years a number of chemistry-climate models have been developed with an emphasis on the stratosphere. Such models cover a wide range of time scales of integration and vary considerably in co...
Quantitative performance metrics for stratospheric-resolving chemistry-climate models
Quantitative performance metrics stratospheric-resolving chemistry-climate models
2008/11/20
A set of performance metrics is applied to stratospheric-resolving chemistry-climate models (CCMs) to quantify their ability to reproduce key processes relevant for stratospheric ozone. The same metri...
