The Global Ozone Monitoring Experiment (GOME) is a new instrument aboard ESA's 2nd European Remote Sensing Satellite (ERS-2), which was launched in April 1995. The main scientiic objective of the GOME mission is to determine the global distribution of ozone and several other trace gases, which play an important role in the ozone chemistry of the Earth's(More)
Emissions from fossil fuel combustion and biomass burning reduce local air quality and affect global tropospheric chemistry. Nitrogen oxides are emitted by all combustion processes and play a key part in the photochemically induced catalytic production of ozone, which results in summer smog and has increased levels of tropospheric ozone globally. Release of(More)
INTRODUCTION Nitrogen oxides play an important role in the chemistry of earth's atmosphere. In the troposphere, they provide the only chemical source for ozone, arguably the most important radical in the lower atmosphere. Nitrogen oxides are central in the formation of photochemical smog in the industrialised countries and also in regions with intense(More)
The Orbiting Carbon Observatory (OCO) mission will make the first global, space-based measurements of atmospheric carbon dioxide (CO 2) with the precision, resolution, and coverage needed to characterize CO 2 sources and sinks on regional scales. The measurement approach and instrument specifications were determined through an analysis of existing carbon(More)
21 We construct global budgets of atmospheric glyoxal and methylglyoxal with the goal of 22 quantifying their potential for global secondary organic aerosol (SOA) formation via 23 irreversible uptake by aqueous aerosols and clouds. We conduct a detailed simulation of 24 glyoxal and methylglyoxal in the GEOS-Chem global 3-D model including our best 25(More)

We combine CO column measurements from the MOPITT, AIRS, SCIAMACHY, and TES satellite instruments in a full-year (May 2004–April 2005) global inversion of CO sources at 4 • ×5 • spatial resolution and monthly temporal resolution. The inversion uses the GEOS-Chem chemical transport model (CTM) and its adjoint applied to MO-PITT, AIRS, and SCIAMACHY.(More)
The remote sensing of the atmospheric greenhouse gases methane (CH 4) and carbon dioxide (CO 2) in the troposphere from instrumentation aboard satellites is a new area of research. In this manuscript, results obtained from observations of the up-welling radiation in the near-infrared by SCIAMACHY on board ENVISAT are presented. Vertical columns of CH 4 , CO(More)
The near-infrared nadir spectra measured by SCIAMACHY on-board ENVISAT contain information on the vertical columns of important atmospheric trace gases such as carbon monoxide (CO), methane (CH 4), and carbon dioxide (CO 2). The scientific algorithm WFM-DOAS has been used to retrieve this information. For CH 4 and CO 2 also column averaged mixing ratios(More)
Tropospheric NO 2 plays a variety of significant roles in atmospheric chemistry. In the troposphere it is one of the most significant precursors of photochemical ozone (O 3) production and nitric acid (HNO 3). In this study tro-pospheric NO 2 columns were calculated by the fully coupled chemistry-climate model ECHAM4.L39(DLR)/CHEM. These have been compared(More)
