The stratospheric balloon-borne UV-visible spectrometers AMON and SALOMON, which use stars and Moon as light source, respectively, are involved in the validation of the UV-visible spectrometer GOMOS onboard ENVISAT, which uses also stars as light source. A low spectral resolution UV-visible spectrometer, AMON-RA, is also implanted in the AMON gondola, for the analysis of the chromatic scintillation effect. A flight of SALOMON occurred in September 19, 2002, at mid latitude from Aire sur 1'Adour, France. An AMON (and AMON-RA) flight occurred at high latitude from Kiruna (northern Sweden) on March 1, 2003. The vertical profiles are compared to those obtained by GOMOS. Taking into account the effect of the chromatic scintillation on the transmission spectra, recommendations will be proposed in order to improve the GOMOS retrievals.
