Description of the payload

SALOMON is a balloon-borne UV-visible spectrometer designed, like its predecesor AMON, to acquire vertical profiles of O3, NO2, NO3, OClO and OBrO as well as the extinction coefficient of aerosols, at altitudes between 15 and 40 km. SOLOMON uses a remote measurement technique (remote-sensing) by using the moon as source of light. The pointing system, the pivot and the gondola were developed at the Laboratoire de Physique et Chimie de l'Environnement (LPCE), whereas the SAOZ-type spectrometer it carries is the result of joint work with the CNRS Service d'Aéronomie.

The instrument work in automatic mode during flight (including start-up, pointing, spectre acquisition and shut-down). The gondola weighs only 85 kilograms, making both launch and flight easier than with AMON.

Between October 1998 and january 2006, SALOMON performed ten successful flights in mid and high latitude. Since 2007 on it was replaced by an improved version denominated SALOMON-N2.

SALOMON was involved in validation programmes for the ODIN and ENVISAT satellites, as well as in national programmes for measuring nitrogen oxides and stratospheric aerosols.
