Wintertime pollution over the Eastern Indo-Gangetic Plains as observed from MOPITT, CALIPSO and tropospheric ozone residual data
Wintertime pollution the Eastern Indo-Gangetic Plains tropospheric ozone residual data
2010/12/28
A large wintertime increase in pollutants has been observed over the eastern parts of the Indo Gangetic Plains. We use improved version 4 carbon monoxide (CO) retrievals from the Measurements of Pollu...
Present and future impact of aircraft, road traffic and shipping emissions on global tropospheric ozone
global tropospheric ozone aircraft road traffic shipping emissions
2010/12/28
In this study, the LMDz-INCA climate-chemistry model and up-to-date global emission inventories are used to investigate the "present" (2000) and future (2050) impacts of transport emissions (road traf...
Vertical structure of Antarctic tropospheric ozone depletion events: characteristics and broader implications
Vertical structure Antarctic tropospheric ozone depletion events characteristics and broader implications
2010/8/25
The majority of tropospheric ozone depletion event (ODE) studies have focussed on time-series measurements, with comparatively few studies of the vertical component. Those that exist have almost exclu...
Snow-sourced bromine and its implications for polar tropospheric ozone
Snow-sourced bromine polar tropospheric ozone
2010/8/25
In the last two decades, significant depletion of boundary layer ozone (ozone depletion events, ODEs) has been observed in both Arctic and Antarctic spring. ODEs are attributed to catalytic destructio...
Tropospheric ozone variations at the Nepal Climate Observatory-Pyramid (Himalayas, 5079 m a.s.l.) and influence of deep stratospheric intrusion events
Tropospheric ozone the Nepal Climate Observatory-Pyramid deep stratospheric intrusion events
2010/8/16
The paper presents the first 2 years of continuous surface ozone (O3) observations and systematic assessment of the influence of stratospheric intrusions (SI) at the Nepal Climate Observatory at Pyram...
Are there urban signatures in the tropospheric ozone column products derived from satellite measurements?
urban signatures the tropospheric ozone column products satellite measurements
2010/8/13
In view of the proposed geostationary satellite missions to monitor air quality from space, it is important to first assess the capability of the current suite of satellite instruments to provide info...
Intercomparison methods for satellite measurements of atmospheric composition: application to tropospheric ozone from TES and OMI
satellite measurements atmospheric composition tropospheric ozone TES OMI
2010/8/13
We analyze the theoretical basis of three different methods to validate and intercompare satellite measurements of atmospheric composition, and apply them to tropospheric ozone retrievals from the Tro...
IASI observations of seasonal and day-to-day variations of tropospheric ozone over three highly populated areas of China: Beijing, Shanghai, and Hong Kong
IASI observations seasonal and day-to-day variations tropospheric ozone three highly populated areas of China
2010/8/12
IASI observations of tropospheric ozone over the Beijing, Shanghai and Hong Kong areas during one year (2008) have been analysed, demonstrating the capability of space-borne infrared nadir measurement...
Tropospheric ozone from IASI: comparison of different inversion algorithms and validation with ozone sondes in the northern middle latitudes
Tropospheric ozone IASI ozone sondes northern middle latitudes
2009/12/31
This paper presents a first statistical validation of tropospheric ozone products derived from measurements of the IASI satellite instrument. Since the end of 2006, IASI (Infrared Atmospheric Sounding...
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...
Evaluation of tropospheric ozone columns derived from assimilated 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...
Measurements of total and tropospheric ozone from IASI: comparison with correlative satellite, ground-based and ozonesonde observations
tropospheric ozone IASI correlative satellite ground-based ozonesonde observations
2009/9/2
In this paper, we present measurements of total and tropospheric ozone, retrieved from infrared radiance spectra recorded by the Infrared Atmospheric Sounding Interferometer (IASI), which was launched...
The influence of biogenic emissions from Africa on tropical tropospheric ozone during 2006: a global modeling study
biogenic emissions Africa tropical tropospheric ozone
2009/8/18
We have performed simulations using a 3-D global chemistry-transport model to investigate the influence that biogenic emissions from the African continent exert on the composition of the troposphere i...
BrO, blizzards, and drivers of polar tropospheric ozone depletion events
BrO blizzards polar tropospheric ozone depletion events
2009/7/23
The source of bromine that drives polar boundary layer ozone depletion events (ODEs) is still open to some debate. While ODEs are generally noted to form under conditions of a shallow stable boundary ...
Accurate satellite-derived estimates of the tropospheric ozone impact on the global radiation budget
Accurate satellite-derived estimates tropospheric ozone global radiation budget
2009/7/15
Estimates of the radiative forcing due to anthropogenically-produced tropospheric O3 are derived primarily from models. Here, we use tropospheric ozone and cloud data from several instruments in the A...
