Air mass factor formulation for spectroscopic measurements from satellites: Application to formaldehyde retrievals from the Global Ozone Monitoring Experiment
(Wiley-Blackwell, 2001)
We present a new formulation for the air mass factor (AMF) to convert slant column measurements of optically thin atmospheric species from space into total vertical columns. Because of atmospheric scattering, the AMF depends ...
A tropospheric ozone maximum over the Middle East
(Wiley-Blackwell, 2001)
The GEOS-CHEM global 3-D model of tropospheric chemistry predicts a summertime O3 maximum over the Middle East, with mean mixing ratios in the middle and upper troposphere in excess of 80 ppbv. This model feature is ...
Sources of tropospheric ozone along the Asian Pacific Rim: An analysis of ozonesonde observations
(Wiley-Blackwell, 2002)
The sources contributing to tropospheric ozone over the Asian Pacific Rim in different seasons are quantified by analysis of Hong Kong and Japanese ozonesonde observations with a global three-dimensional (3-D) chemical ...
An improved retrieval of tropospheric nitrogen dioxide from GOME
(Wiley-Blackwell, 2002)
We present a retrieval of tropospheric nitrogen dioxide (NO2) columns from the Global Ozone Monitoring Experiment (GOME) satellite instrument that improves in several ways over previous retrievals, especially in the ...
Background ozone over the United States in summer: Origin, trend, and contribution to pollution episodes
(Wiley-Blackwell, 2002)
Observations indicate that ozone (O3) concentrations in surface air over the United States in summer contain a 20–45 ppbv background contribution, presumably reflecting transport from outside the North American boundary ...
Interpretation of TOMS observations of tropical tropospheric ozone with a global model and in situ observations
(American Geophysical Union, 2002)
We interpret the distribution of tropical tropospheric ozone columns (TTOCs) from the Total Ozone Mapping Spectrometer (TOMS) by using a global three-dimensional model of tropospheric chemistry (GEOS-CHEM) and additional ...
Transatlantic transport of pollution and its effects on surface ozone in Europe and North America
(Wiley-Blackwell, 2002)
We examine the transatlantic transport of anthropogenic ozone and its impact on surface ozone in Europe and North America by using a 5-year (1993–1997) simulation with the GEOS-CHEM global three-dimensional model of ...
Sources and budgets for CO and O3 in the northeastern Pacific during the spring of 2001: Results from the PHOBEA-II Experiment
(Wiley-Blackwell, 2003)
Ground and airborne measurements of CO, ozone, and aerosols were obtained in the northeastern (NE) Pacific troposphere during 9 March–31 May 2001 as part of the PHOBEA-II project (Photochemical Ozone Budget of the Eastern ...
Transport pathways for Asian pollution outflow over the Pacific: Interannual and seasonal variations
(Wiley-Blackwell, 2003)
The meteorological pathways contributing to Asian pollution outflow over the Pacific are examined with a global three-dimensional model analysis of CO observations from the Transport and Chemical Evolution over the Pacific ...
Fresh air in the 21st century?
(Wiley-Blackwell, 2003)
Ozone is an air quality problem today for much of the world's population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the ...
