Abstract : Positive ion composition measurements obtained with rocket-borne mass spectrometers in the lower ionosphere are presented. The current situation regarding the water cluster ions in the D region is considered. Evidence is given in favor of an ambient instead of a contamination origin for the water cluster ions, although the exact processes for the formation of these ions in the atmosphere are still not definitely established. A theory is discussed whereby water cluster ions may be created through the ionization of small water conglomerates, which are assumed both to be present in the mesosphere and to have very low ionization thresholds.
