Millimeter wave spectroscopic measurements of stratospheric and mesospheric constituents over the Italian Alps: stratospheric ozone
millimeter-wave spectroscopy stratospheric ozone isentropic transport
2015/9/2
Measurements of rotational lines emitted by middle atmospheric trace gases have been carried out from the Alpine
station of Testa Grigia (45.9°N, 7.7°E, elev. 3500 m) by means of a Ground-Based Milli...
Attribution of observed changes in stratospheric ozone and temperature
observed changes stratospheric ozone temperature
2011/2/24
Three recently-completed sets of simulations of multiple chemistry-climate models with greenhouse gases only, with all anthropogenic forcings, and with anthropogenic and natural forcings, allow the ca...
Analysis of a rapid increase of stratospheric ozone during late austral summer 2008 over Kerguelen (49.4° S, 70.3° E)
stratospheric ozone late austral summer 2008 Kerguelen (49.4° S, 70.3° E)
2011/1/19
This paper reports on an increase of ozone event observed over Kerguelen (49.4° S, 70.3° E) in relationship with large-scale isentropic transport. This is evidenced by ground-based observations (co-lo...
Attribution of stratospheric ozone trends to chemistry and transport: a modelling study
stratospheric ozone chemistry transport a modelling study
2010/12/28
The decrease of the concentration of ozone depleting substances (ODSs) in the stratosphere over the past decade raises the question to what extent observed changes in stratospheric ozone over this per...
Spatial, temporal, and vertical variability of polar stratospheric ozone loss in the Arctic winters 2004/2005–2009/2010
polar stratospheric ozone the Arctic winters
2010/10/21
The polar stratospheric ozone loss during the Arctic winters 2004/2005–2009/2010 is investigated by using high resolution simulations from the chemical transport model Mimosa-Chim and observations fro...
The potential to narrow uncertainty in projections of stratospheric ozone over the 21st century
stratospheric ozone the 21st century
2010/10/11
Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, includi...
Multi-model assessment of stratospheric ozone return dates and ozone recovery in CCMVal-2 models
stratospheric ozone return dates ozone recovery CCMVal-2 models
2010/10/11
Projections of stratospheric ozone from a suite of chemistry-climate models (CCMs) have been analyzed. In addition to a reference simulation where anthropogenic halogenated ozone depleting substances ...
Quantifying the contributions to stratospheric ozone changes from ozone depleting substances and greenhouse gases
stratospheric ozone ozone depleting substances greenhouse gases
2010/9/21
A state-of-the-art chemistry climate model coupled to a three-dimensional ocean model is used to produce three experiments, all seamlessly covering the period 1950–2100, forced by different combinatio...
Validation of Ozone Monitoring Instrument (OMI) ozone profiles and stratospheric ozone columns with Microwave Limb Sounder (MLS) measurements
Ozone Monitoring Instrument ozone profiles stratospheric ozone columns Microwave Limb Sounder measurements
2010/3/16
We validate OMI ozone profiles between 0.22–215 hPa and stratospheric ozone columns down to 215 hPa (SOC215) against v2.2 MLS data from 2006. The validation demonstrates convincingly that SOC can be d...
Sensitivity of polar stratospheric ozone loss to uncertainties in chemical reaction kinetics
polar stratospheric ozone uncertainties chemical reaction kinetics
2009/11/19
The impact and significance of uncertainties in model calculations of stratospheric ozone loss resulting from known uncertainty in chemical kinetics parameters is evaluated in trajectory chemistry sim...
The effect of nonlinearity in CO2 heating rates on the attribution of stratospheric ozone and temperature changes
CO2 heating rates stratospheric ozone temperature changes
2009/11/19
An analysis of the attribution of past and future changes in stratospheric ozone and temperature to anthropogenic forcings is presented. The analysis is an extension of the study of Shepherd and Jonss...
Upper stratospheric ozone decrease events due to a positive feedback between ozone and the ozone dissociation rate
Upper stratospheric ozone decrease events positive feedback ozone dissociation rate
2009/10/30
Ozone measurements taken with a ground based microwave instrument at Lindau (51.66° N, 10.13° E) over some years showed strong ozone decrease events within the stratopause region, particularly during ...
Evolution of stratospheric ozone and water vapour time series studied with satellite measurements
stratospheric ozone water vapour time series satellite measurements
2009/8/25
The long term evolution of stratospheric ozone and water vapour has been investigated by extending satellite time series to April 2008. For ozone, we examine monthly average ozone values from various ...
Classification of Northern Hemisphere stratospheric ozone and water vapor profiles by meteorological regime
Northern Hemisphere stratospheric ozone water vapor profiles meteorological regime
2009/8/25
The subtropical and polar upper troposphere fronts and the polar vortex serve as the boundaries to divide the Northern Hemisphere into four meteorological regimes. These regimes are defined as (1) the...
