Effect of Climate Change on Air Quality
(Elsevier, 2009)
Air quality is strongly dependent on weather and is therefore sensitive to climate change. Recent studies have provided estimates of this climate effect through correlations of air quality with meteorological variables, ...
Climate forcings in Goddard Institute for Space Studies SI2000 simulations
(Wiley-Blackwell, 2002)
We define the radiative forcings used in climate simulations with the SI2000 version of the Goddard Institute for Space Studies (GISS) global climate model. These include temporal variations of well-mixed greenhouse gases, ...
Sources and chemistry of nitrogen oxides over the tropical Pacific
(Wiley-Blackwell, 2003)
We examine the sources and chemistry affecting nitrogen oxides (NOx = NO + NO2) over the tropical Pacific (30°S–20°N) using observations from the Pacific Exploratory Mission to the Tropics B (PEM-Tropics B) aircraft mission ...
Global and regional decreases in tropospheric oxidants from photochemical effects of aerosols
(Wiley-Blackwell, 2003)
We evaluate the sensitivity of tropospheric OH, O3, and O3 precursors to photochemical effects of aerosols not usually included in global models: (1) aerosol scattering and absorption of ultraviolet radiation and (2) ...
Ozone production in transpacific Asian pollution plumes and implications for ozone air quality in California
(Wiley-Blackwell, 2004)
We examine the ozone production efficiency in transpacific Asian pollution plumes, and the implications for ozone air quality in California, by using aircraft and surface observations in April–May 2002 from the Intercontinental ...
Impact of Asian emissions on observations at Trinidad Head, California, during ITCT 2K2
(Wiley-Blackwell, 2004)
Field measurements of a wide suite of trace gases and aerosols were carried out during April and May 2002, along with extensive chemical transport modeling, as part of the NOAA Intercontinental Transport and Chemical ...
Evaluation of GOME satellite measurements of tropospheric NO 2 and HCHO using regional data from aircraft campaigns in the southeastern United States
(Wiley-Blackwell, 2004)
We compare tropospheric measurements of nitrogen dioxide (NO2) and formaldehyde (HCHO) from the Global Ozone Monitoring Experiment (GOME) satellite instrument with in situ measurements over eastern Texas and the southeast ...
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 ...
Simulated observation of tropospheric ozone and CO with the Tropospheric Emission Spectrometer (TES) satellite instrument
(Wiley-Blackwell, 2002)
The Tropospheric Emission Spectrometer (TES) on board NASA's Aura satellite (to be launched in 2004) will provide measurements of global distributions of ozone, CO, and other key chemical species in the troposphere. In ...
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 ...
