Influence of meteorological variability on interannual variations of springtime boundary layer ozone over Japan during 1981–2005
meteorological variability springtime boundary layer ozone Japan
2009/9/2
We investigated the influence of meteorological variability on the interannual variation of springtime boundary layer ozone over Japan during 1981–2005 by multiyear simulations with the Models-3 Commu...
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...
Increasing surface ozone concentrations in the background atmosphere of Southern China, 1994–2007
Increasing surface ozone concentrations background atmosphere Southern China
2009/9/2
Tropospheric ozone is of great importance with regard to air quality, atmospheric chemistry, and climate change. In this paper we report the first continuous record of surface ozone in the background ...
An overview of two years of ozone radio soundings over Cotonou as part of AMMA
ozone radio soundings Cotonou AMMA
2009/9/2
vertical profiles over Cotonou, Benin, have been measured during a 26 month period (December 2004–January 2007). These regular measurements broadly document the seasonal and interannual variability of...
Factors controlling the distribution of ozone in the West African lower troposphere during the AMMA（African Monsoon Multidisciplinary Analysis）wet season campaign
Factors controlling ozone West African lower troposphere AMMA wet season
2009/9/2
Ozone and its precursors were measured on board the Facility for Airborne Atmospheric Measurements (FAAM) BAe 146 Atmospheric Research Aircraft during the monsoon season 2006 as part of the African Mo...
Effect of regional precursor emission controls on long-range ozone transport – Part 1: Short-term changes in ozone air quality
regional precursor emission controls long-range ozone transport ozone air quality
2009/8/25
Observations and models demonstrate that ozone and its precursors can be transported between continents and across oceans. We model the influences of 10% reductions in anthropogenic nitrogen oxide (NO...
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...
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...
Dynamical modes associated with the Antarctic ozone hole
Dynamical modes Antarctic ozone hole
2009/8/7
Generalized Maximum Covariance Analysis (GMCA) has been developed and applied to diagnosing the dynamical modes associated with variations in the Antarctic spring ozone hole. GMCA is used to identify ...
Long-term changes in UT/LS ozone between the late 1970s and the 1990s deduced from the GASP and MOZAIC aircraft programs and from ozonesondes
UT/LS ozone GASP MOZAIC aircraft programs ozonesondes
2009/8/7
We present ozone measurements of the Global Atmospheric Sampling Program (GASP) performed from four commercial and one research aircraft in the late 1970s to compare them with respective measurements ...
Technical Note: Functional sliced inverse regression to infer temperature, water vapour and ozone from IASI data
Functional sliced inverse regression infer temperature water vapour ozone IASI data
2009/8/7
A retrieval algorithm that uses a statistical strategy based on dimension reduction is proposed. The methodology and details of the implementation of the new algorithm are presented and discussed. The...
Exposure-plant response of ambient ozone over the tropical Indian region
Exposure-plant response ambient ozone tropical Indian region
2009/8/7
A high resolution regional chemistry-transport model has been used to study the distribution of exposure-plant response index (AOT40, Accumulated exposure Over a Threshold of 40 ppb, expressed as ppb ...
