The authors investigate the influence of El Niño on midtropospheric CO2 from the Atmospheric Infrared Sounder (AIRS) and the Model for Ozone and Related Chemical Tracers, version 2 (MOZART-2). AIRS midtropospheric CO2 data are used to study the temporal and spatial variability of CO2 in response to El Niño. CO2 differences between the central and western(More)
Midtropospheric CO2 retrievals from the Atmospheric Infrared Sounder (AIRS) were used to explore the influence of stratospheric sudden warming (SSW) on CO2 in the middle to upper troposphere. To choose the SSW events that had strong coupling between the stratosphere and troposphere, the authors applied a principal component analysis to the NCEP/Department(More)
[1] Using in situ measurements, we find a semiannual oscillation (SAO) in the midtropospheric and surface CO2. Chemistry transport models (2-D Caltech/JPL model, 3-D GEOS-Chem, and 3-D MOZART-2) are used to investigate possible sources for the SAO signal in the midtropospheric and surface CO2. From model sensitivity studies, it is revealed that the SAO(More)
The impacts of El Niño–Southern Oscillation (ENSO) on the tropical total column ozone, the tropical tropopause pressure, and the 3.5-yr ozone signal in the midlatitude total column ozone were examined using the Goddard Earth Observing System Chemistry–Climate Model (GEOS CCM). Observed monthly mean sea surface temperature and sea ice between 1951 and 2004(More)
Two meteorological reanalysis datasets are analyzed to determine the mechanical energies of the global atmosphere in the El Niño and La Niña years. The general consistency of the mean energy components between the two datasets reveals ;1%–3% increase and ;2%–3% decrease in the mean energies in the El Niño years and La Niña years, respectively. These(More)
[1] Mid‐tropospheric CO2 retrieved from the Atmospheric Infrared Sounder (AIRS) was used to investigate CO2 interannual variability over the Indo‐Pacific region. A signal with periodicity around two years was found for the AIRS mid‐tropospheric CO2 for the first time, which is related to the Tropospheric Biennial Oscillation (TBO) associated with the(More)
EPA’s Community Multiscale Air Quality (CMAQ) model was used to investigate the influence of lateral boundary conditions (LBCs) on ozone simulation. Meteorological fields used to drive the model were from the fifth generation Mesoscale Model (MM5). Emission files were prepared from the Sparse Matrix Operating Kernel for Emissions (SMOKE) model.
