Aeronomical balloon experiments

Aeronomical balloon observations can be divided into two categories: in situ measurements of atmospheric constituents and other physical parameters, and measurements of the atmospheric transmission characteristics of the layers above the balloon. The optical experiments, in the infrared, the visible, the ultraviolet and the X-ray parts of the electromagnetic spectrum are discussed in detail whereas a brief review is given of in situ measurements of atmospheric composition, of the electric field and of cosmic dust.
