Content:
This volume addresses a number of experimental techniques and methods for the treatment of data introduced in the last ten years or so in different fields of the atmospheric sciences. Considerable emphasis has been given since their introduction to the use of satellites or space borne measurements with a recent example being the important results obtained with UARS. Of particular interest are the airborne instruments developed for the stratospheric measurement campaign organized by the NASA since 1976 to study the ozone hole and followed later by similar experiments to study the high-latitude.
