Abstract: The aeronomy of Jupiter's atmosphere at pressures <25 mb is surveyed. Attention is drawn to those areas most in need of further work, including both planetary and laboratory studies. The heat balance is still uncertain at ...

Abstract: The Jeans-Spitzer treatment of atmospheric escape by evaporation must be supplemented, for a mixture of gases, by a discussion of the mutual diffusion and mixing of the components. A recent description for the atmosphere ...

Abstract: The agronomy of hydrogen and its compounds is discussed in a simplified model intended to represent a diurnal and global average. Vertical transport by eddy and molecular diffusion is included for the major components H2O, ...

Abstract: A height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10?16 g cm?2 s?1 (44 metric tons per day) and the velocity distribution of Southworth and Sekanina, which has a mean of 14.5 km s?1. ...
