Influence of scintillation on quality of ozone monitoring by GOMOS
scintillation quality ozone monitoring GOMOS
2009/12/31
Stellar light passing through the Earth atmosphere is affected by refractive effects, which should be taken into account in retrievals from stellar occultation measurements. Scintillation caused by ai...
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...
Surface ozone trend details and interpretations in Beijing, 2001–2006
Surface ozone trend details interpretations Beijing
2009/12/3
Beijing is a megacity situated in the rapidly developing Beijing-Tianjin-Hebei region of northern China. In this study, we analyze data on ozone and nitrogen oxide levels obtained at six urban sites i...
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...
Evaluating the potential of IASI ozone observations to constrain simulated surface ozone concentrations
IASI ozone observations to constrain simulated surface ozone concentrations
2009/11/19
A tracer study has been performed for two summers in 2003 and 2004 with a regional chemistry-transport model in order to evaluate the potential constraint that tropospheric ozone observations from nad...
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...
Clouds, photolysis and regional tropospheric ozone budgets
Clouds photolysis regional tropospheric ozone budgets
2009/11/19
We use a three-dimensional chemical transport model to examine the shortwave radiative effects of clouds on the tropospheric ozone budget. In addition to looking at changes in global concentrations as...
Retrieval of water vapor profile in the mesosphere from satellite ozone and hydroxyl measurements by the basic dynamic model of mesospheric photochemical system
water vapor profile satellite ozone hydroxyl measurements basic dynamic model mesospheric photochemical system
2009/11/19
We propose an indirect method for retrieving a number of significant minor gas constituents of the atmosphere. The technique is based on the use of so-called basic dynamic models of atmospheric photoc...
Evaluation of tropospheric ozone columns derived from assimilated GOME ozone profile observations
tropospheric ozone columns GOME ozone profile observations
2009/11/9
Tropospheric O3 column estimates are produced and evaluated from spaceborne O3 observations by the subtraction of assimilated O3 profile observations from total column observations, the so-called Trop...
Technical Note: A SAGE-corrected SBUV zonal-mean ozone data set
SAGE-corrected SBUV zonal-mean ozone data set
2009/11/9
A stratospheric vertically resolved, monthly, zonal-mean ozone data set based on Satellite Aerosol and Gas Experiment (SAGE) and Solar Backscatter UltraViolet (SBUV) data spanning 1979–2005 is present...
Rates and regimes of photochemical ozone production over Central East China in June 2006: a box model analysis using comprehensive measurements of ozone precursors
photochemical ozone Central East China comprehensive measurements ozone precursors
2009/11/9
An observation-based box model approach was undertaken to estimate concentrations of OH, HO2, and RO2 radicals and the net photochemical production rate of ozone at the top of Mount Tai, located in th...
Comparison of aerosol optical depths from the Ozone Monitoring Instrument (OMI) on Aura with results from airborne sunphotometry, other space and ground measurements during MILAGRO/INTEX-B
