Atmospheric three-dimensional inverse modeling of regional industrial emissions and global oceanic uptake of carbon tetrachloride
regional industrial emissions global oceanic carbon tetrachloride
2010/11/29
Carbon tetrachloride (CCl4) has substantial stratospheric ozone depletion potential and its consumption is controlled under the Montreal Protocol and its amendments. We implement a Kalman filter using...
Regional-scale geostatistical inverse modeling of North American CO2 fluxes: a synthetic data study
Regional-scale geostatistical North American CO2 fluxes a synthetic data study
2010/8/16
A series of synthetic data experiments is performed to investigate the ability of a regional atmospheric inversion to estimate grid-scale CO2 fluxes during the growing season over North America. The i...

Hydrochlorofluorocarbon hydrofluorocarbon emissions East Asia inverse modeling
2010/8/12
The emissions of three hydrochlorofluorocarbons, HCFC-22 (CHClF2), HCFC-141b (CH3CCl2F) and HCFC-142b (CH3CClF2) and three hydrofluorocarbons, HFC-23 (CHF3), HFC-134a (CH2FCF3) and HFC-152a (CH3CHF2) ...
Inverse modeling of European CH4 emissions: sensitivity to the observational network
European CH4 emissions observational network
2010/2/21
Inverse modeling is widely employed to provide "top-down" emission estimates using atmospheric measurements. Here, we analyze the dependence of derived CH4 emissions on the sampling frequency and dens...
Inverse modeling and mapping US air quality influences of inorganic PM2.5 precursor emissions using the adjoint of GEOS-Chem
US air quality influences inorganic PM2.5 precursor emissions GEOS-Chem
2009/8/25
Influences of specific sources of inorganic PM2.5 on peak and ambient aerosol concentrations in the US are evaluated using a combination of inverse modeling and sensitivity analysis. First, sulfate an...
The zonal structure of tropical O3 and CO as observed by the Tropospheric Emission Spectrometer in November 2004 – Part 1: Inverse modeling of CO emissions
Tropospheric Emission Spectrometer Inverse modeling CO emissions
2009/6/16
We conduct an inverse modeling analysis of measurements of atmospheric CO from the TES and MOPITT satellite instruments using the GEOS-Chem global chemical transport model to quantify emissions of CO ...
Inverse modeling of CO2 sources and sinks using satellite data: a synthetic inter-comparison of measurement techniques and their performance as a function of space and time
CO2 sources synthetic inter-comparison function of space and time
2009/2/24
Currently two polar orbiting satellite instruments measure CO2 concentrations in the Earth's atmosphere, while other missions are planned for the coming years. In the future such instruments might be...
An inverse modeling procedure to determine particle growth and nucleation rates from measured aerosol size distributions
inverse modeling procedure nucleation rates aerosol size distributions
2009/1/13
Classical nucleation theory is unable to explain the ubiquity of nucleation events observed in the atmosphere. This shows a need for an empirical determination of the nucleation rate. Here we present ...
Diagnosing recent CO emissions and ozone evolution in East Asia using coordinated surface observations, adjoint inverse modeling, and MOPITT satellite data
CO ozone evolution East Asia MOPITT satellite
2008/11/13
Simultaneous ground-based measurements of ozone (O3) and carbon monoxide (CO) were conducted in March 2005 as part of the East Asian Regional Experiment (EAREX) 2005 under the umbrella of the Atmosphe...
Retrieving global aerosol sources from satellites using inverse modeling
Retrieving global aerosol sources satellites inverse modeling
2008/10/27
Understanding aerosol effects on global climate requires knowing the global distribution of tropospheric aerosols. By accounting for aerosol sources, transports, and removal processes, chemical transp...
