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 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 ...
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 ...
Global chemical model analysis of biomass burning and lightning influences over the South Pacific in austral spring
(Wiley-Blackwell, 2002)
A global three-dimensional model of tropospheric chemistry driven by reanalyzed European Centre for Medium-Range Weather Forecasts meteorological data is used to examine the sources of O3, CO, and nitrogen oxides (NOx = ...
Stratospheric versus pollution influences on ozone at Bermuda: Reconciling past analyses
(Wiley-Blackwell, 2002)
Conflicting interpretations of the spring ozone maximum observed at Bermuda (32°N, 65°W) have fueled the debate on stratospheric influence versus tropospheric production as sources of tropospheric ozone. We use a global ...
Methyl iodide: Atmospheric budget and use as a tracer of marine convection in global models
(Wiley-Blackwell, 2002)
We simulate the oceanic and atmospheric distribution of methyl iodide (CH3I) with a global 3-D model driven by assimilated meteorological observations from the Goddard Earth Observing System of the NASA Data Assimilation ...
