Abstract: Aircraft emissions impact the atmosphere in a variety of ways, including enhancing greenhouse gases, especially water vapor and carbon dioxide, in the upper troposphere and lower stratosphere, forming persistent contrails, ...

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: 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: 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 ...
