Global inventory of nitrogen oxide emissions constrained by space-based observations of NO2 columns
(Wiley-Blackwell, 2003)
We use tropospheric NO2 columns from the Global Ozone Monitoring Experiment (GOME) satellite instrument to derive top-down constraints on emissions of nitrogen oxides (NOx ≡ NO + NO2), and combine these with a priori ...
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) ...
In situ measurements of HCN and CH3CN over the Pacific Ocean: Sources, sinks, and budgets
(Wiley-Blackwell, 2003)
We report the first in situ measurements of hydrogen cyanide (HCN) and methyl cyanide (CH3CN, acetonitrile) from the Pacific troposphere (0–12 km) obtained during the NASA Transport and Chemical Evolution over the Pacific ...
Sources of carbonaceous aerosols over the United States and implications for natural visibility
(Wiley-Blackwell, 2003)
We use a global three-dimensional model (GEOS-CHEM) to better quantify the sources of elemental carbon (EC) and organic carbon (OC) aerosols in the United States through simulation of year-round observations for 1998 at a ...
Transport and Chemical Evolution over the Pacific (TRACE-P) aircraft mission: Design, execution, and first results
(Wiley-Blackwell, 2003)
The NASA Transport and Chemical Evolution over the Pacific (TRACE-P) aircraft mission was conducted in February–April 2001 over the NW Pacific (1) to characterize the Asian chemical outflow and relate it quantitatively to ...
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 ...
Mapping isoprene emissions over North America using formaldehyde column observations from space
(Wiley-Blackwell, 2003)
We present a methodology for deriving emissions of volatile organic compounds (VOC) using space-based column observations of formaldehyde (HCHO) and apply it to data from the Global Ozone Monitoring Experiment (GOME) ...
Interactions between tropospheric chemistry and aerosols in a unified general circulation model
(Wiley-Blackwell, 2003)
A unified tropospheric chemistry-aerosol model has been developed within the Goddard Institute for Space Studies general circulation model (GCM). The model includes a detailed simulation of tropospheric ozone-NOx-hydrocarbon ...
Biomass burning emission inventory with daily resolution: Application to aircraft observations of Asian outflow
(Wiley-Blackwell, 2003)
We develop a daily-resolved global emission inventory for biomass burning using AVHRR satellite observations of fire activity corrected for data gaps and scan angle biases. We implemented this inventory in a global ...
