Photochemistry of the atmosphere of Titan: comparison between model and observations.
The photochemistry of simple molecules containing carbon, hydrogen, nitrogen, and oxygen atoms in the atmosphere of Titan has been investigated using updated chemical schemes and the authors' own estimates of a number of key rate coefficients, which satisfactorily accounts for the concentrations of minor species observed by the Voyager IRIS and UVS instruments.

A photochemical model of the martian atmosphere.
Good agreement between models and observations of CO, O2, O3, and the escape flux of atomic hydrogen can be achieved, using only gas-phase chemistry, by varying the recommended rate constants for the reactions CO + OH and OH + HO2 within their specified uncertainties. Expand
ATMOS stratospheric deuterated water and implications for troposphere‐stratosphere transport
Measurements of the isotopic composition of stratospheric water by the ATMOS instrument are used to infer the convective history of stratospheric air. The average water vapor entering the… Expand
The Cassini Ultraviolet Imaging Spectrograph Investigation
The Cassini Ultraviolet Imaging Spectrograph (UVIS) is part of the remote sensing payload of the Cassini orbiter spacecraft. UVIS has two spectrographic channels that provide images and spectra… Expand
Water vapour in the atmosphere of a transiting extrasolar planet
An analysis of recent observations of the hot Jupiter HD 189733b taken during the transit, when the planet passed in front of its parent star, finds that absorption by water vapour is the most likely cause of the wavelength-dependent variations in the effective radius of the planet. Expand
MOLECULAR SIGNATURES IN THE NEAR-INFRARED DAYSIDE SPECTRUM OF HD 189733b
We have measured the dayside spectrum of HD 189733b between 1.5 and 2.5 μm using the NICMOS instrument on the Hubble Space Telescope. The emergent spectrum contains significant modulation, which we… Expand
The Orbiting Carbon Observatory (OCO) mission
The Orbiting Carbon Observatory (OCO) mission will make the first global, space-based measurements of atmospheric carbon dioxide (CO2) with the precision, resolution, and coverage needed to… Expand
PRODUCTION, ISOTOPIC COMPOSITION, AND ATMOSPHERIC FATE OF BIOLOGICALLY PRODUCED NITROUS OXIDE
The anthropogenic production of greenhouse gases and their consequent effects on global climate have garnered international attention for years. A remaining challenge facing scientists is to… Expand
Unexpected air pollution with marked emission reductions during the COVID-19 outbreak in China
Unexpectedly, extreme particulate matter levels simultaneously occurred in northern China, and synergistic observation analyses and model simulations show that anomalously high humidity promoted aerosol heterogeneous chemistry, along with stagnant airflow and uninterrupted emissions from power plants and petrochemical facilities, contributing to severe haze formation.
