The mole fraction x2 of (H2)2 in equilibrium mixture with H2 under the atmospheric conditions of Jupiter is evaluated from the dimerization equilibrium constant calculated by quantum-chemical treatments and also from the Lennard-Jones potential. The treatments are of an ab initio type with the ...

The seasonal cycle of CO2 mole fraction is damped with elevation. While the amplitude of the seasonal cycle is 28.5 μmol mol 1 at 10 m above the ground, it is only 10.7 μmol mol 1 in the layer of 2500–3000 m corresponding to the lower free atmosphere above the well-mixed boundary...
CO2CO2 Isotopes(CO2)-C-12-O-16(CO2)-C-13-O-16The precision of optically based techniques for long term CO2 monitoring in the atmosphere is approaching the +/- 0.02 mu mol mol(-1 )level, however biases of potentially up to fifteen times greater than this can arise due to differences ...
The computed dimerization equilibrium constant is combined with observed height profiles of temperature and pressure in the Jupiter atmosphere in order to derive the dimeric mole fraction x2 in the partial thermodynamic equilibrium with the monomer. In all the treatments considered, it is found that ...
There is a widely recognized need to improve our understanding of biosphere-atmosphere carbon exchanges in areas of complex terrain including the United States Mountain West. CO2 fluxes over mountainous terrain are often difficult to measure due to unusual and complicated influences associated with ...

Our reanalysis of these data incorporates the effects of limb-darkening based upon the Minnaert approximation model, which provides a much stronger constraint on the cloud structure and methane mole fraction, makes better use of the available data and is also more computationally efficient. We find ...
This study systematically examines the regional uncertainties and biases in carbon dioxide (CO2) mole fractions from two of the state‐of‐the‐art global CO2 analysis products, namely, the Copernicus Atmosphere Monitoring Service (CAMS) real‐time atmospheric analysis from the European Centre for ...
