The achievements and potential of ISO archive for planetary studies

The ISO observations of planetary objects have given several outstanding results. However, the potential from the ISO archive is still high as many observations, or some spectral ranges have not been analysed yet. The most striking example being the ISOCAM observations of Jupiter and Saturn. This situation is due to the difficulty to reduce and calibrate the high flux (Up to 10(6) Jy) planetary observations, to the lack of spectroscopic data or numerical tools to accurately analyse the data, and also because the planetary community focused on the most unexpected observations. The achievements and potential from ISO archive encompasses the atmospheric isotopic composition, the oxygen and hydrocarbon stratospheric chemistry in the Giant Planets and Titan, the cloud structure of Jupiter and Saturn, and the composition of planetary surfaces.
