Trends in the upper atmosphere and ionosphere: Recent progress

Ionosphere and Upper Atmosphere Research with Radars

Upper Atmosphere and Ionosphere of Saturn

This chapter summarizes our current understanding of the upper atmosphere and ionosphere of Saturn. We summarize the available observations and the various relevant models associated with these regions. We describe what is currently known, outline any controversies and indicate how future observations can help in advancing our understanding of the various controlling physical and chemical proce...

Driving Saturn’s magnetospheric periodicities from the upper atmosphere/ionosphere

[1] Saturn’s magnetospheric structure and the intensity of radio frequency emissions from its immediate surroundings are modulated at close to the planet’s rotation period. Analogous rotation-modulated variations at Jupiter are readily interpreted as effects of the non-axisymmetric intrinsic magnetic field. At Saturn, to the contrary, the high level of axial symmetry in the intrinsic field sugg...

Recent Progress in Allergen Immunotherapy

The efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. Immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...

Saturn: atmosphere, ionosphere, and magnetosphere.

The Cassini spacecraft has been in orbit around Saturn since 30 June 2004, yielding a wealth of data about the Saturn system. This review focuses on the atmosphere and magnetosphere and briefly outlines the state of our knowledge after the Cassini prime mission. The mission has addressed a host of fundamental questions: What processes control the physics, chemistry, and dynamics of the atmosphe...
