The aim of this proposal was to provide comprehensive and accurate data on water absorption at short wavelengths. These data were generated using techniques of first principle quantum mechanics that have been successfully applied to both absorption by water vapour at longer wavelengths and other key atmospheric species. Where possible the positions of absorption features were adjusted using laboratory measurements. The resulting line lists are made available to key groups involved monitoring the Earth's atmosphere in the near UV, placed in data depositories and made available to databases such as HITRAN.
