Abstract: Models for the Venus atmosphere and ionosphere are presented and compared with data obtained in the S-band occultation experiment on Mariner 5. Good agreement is found between model and experiment if the Venus atmosphere ...

Abstract: he Hadley system provides an example of a thermally direct circulation; the Ferrel system in contrast provides an example of a thermally indirect circulation. In this study, the authors develop an approach to investigate ...

Abstract: Sources and sinks for atmospheric odd nitrogen are discussed and detailed calculations are presented for the altitude range 0?80 km. The mixing ratio of odd nitrogen is approximately 2?10?9 throughout the troposphere and ...

Abstract: Carbon monoxide, produced in the Venus atmosphere by photolysis of CO2, is removed mainly by reaction with OH. The radical OH is formed in part by photolysis of H2O2, in part by reaction of 0 with H02. Photolysis of HCl ...

Abstract: Detailed calculations are presented for the production of O and CO in the Martian atmosphere. The diffusion equations are solved and results compared with Mariner observations of O and CO in the upper Marian atmosphere. ...

Abstract: Supersonic transport planes currently under development will cruise in the stratosphere and there is concern about possible environmental effects. In particular, NO emitted by these aircraft may catalytically affect ...

Abstract: Growth of nitric acid trihydrate (NAT) particles on background stratospheric aerosols is examined for an isolated air parcel cooled at a uniform rate. The free energy barrier against nucleation and rates of cooling are ...

Abstract: Models for stratosphere temperature and ozone are developed and shown to give good agreement with observational data. The atmosphere is in local radiative equilibrium at heights above about 35 km, and concentrations of ...
