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 ...
Climate response to the increase in tropospheric ozone since preindustrial times: A comparison between ozone and equivalent CO 2 forcings
(Wiley-Blackwell, 2004)
We examine the characteristics of the climate response to anthropogenic changes in tropospheric ozone. Using a general circulation model, we have carried out a pair of equilibrium climate simulations with realistic present-day ...
Eastern Asian emissions of anthropogenic halocarbons deduced from aircraft concentration data
(Wiley-Blackwell, 2003)
The Montreal Protocol restricts production of ozone-depleting halocarbons worldwide. Enforcement of the protocol has relied mainly on annual government statistics of production and consumption of these compounds (bottom-up ...
Sensitivity of population smoke exposure to fire locations in Equatorial Asia
(Elsevier BV, 2015)
Land clearing by fire in Equatorial Asia, a substantial fraction for conversion to
oil palm plantations, can lead to high smoke concentrations across this densely populated region and represents a serious public health ...
Anthropogenic emissions of highly reactive volatile organic compounds in eastern Texas inferred from oversampling of satellite (OMI) measurements of HCHO columns
(IOP Publishing, 2014)
Satellite observations of formaldehyde (HCHO) columns provide top-down constraints on emissions of highly reactive volatile organic compounds (HRVOCs). This approach has been used previously in the US to estimate isoprene ...
Global modeling of tropospheric chemistry with assimilated meteorology: Model description and evaluation
(Wiley-Blackwell, 2001)
We present a first description and evaluation of GEOS-CHEM, a global threedimensional (3-D) model of tropospheric chemistry driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS) ...
General circulation model assessment of direct radiative forcing by the sulfate-nitrate-ammonium-water inorganic aerosol system
(Wiley-Blackwell, 2001)
An on-line simulation of aerosol sulfate, nitrate, ammonium, and water in the Goddard Institute for Space Studies general circulation model (GCM II-prime) has been used to estimate direct aerosol radiative forcing for the ...
Radiative forcing from tropospheric ozone calculated with a unified chemistry-climate model
(Wiley-Blackwell, 1999)
We have developed a global model for the study of chemistry-climate interactions by incorporating a detailed simulation of tropospheric ozone-NOx-hydrocarbon chemistry within a general circulation model (GCM). We present ...
Formaldehyde (HCHO) As a Hazardous Air Pollutant: Mapping Surface Air Concentrations from Satellite and Inferring Cancer Risks in the United States
(American Chemical Society (ACS), 2017-05-05)
Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the U.S. Environmental Protection Agency (EPA), not including ozone and particulate matter. ...
