A requirement has been identified by the ETWS and the ETMC of the JCOMM Data Management Programme Area DMPA, for the establishment of a JCOMM Extremes Wave Data Base for use in model validation and validation of remotely-sensed waves, where such models and algorithms suffer from lack of sufficient data. This database would be populated with measured wave data where the significant wave height exceeded 14 metres, with appropriate accompanying metadata. The 9th Waves Workshop expressed strong interest in expanding the scope of the extreme wave data archive, to include satellite estimates, as well as data from wave radars such as WaMoS or MIROS. The rationale for the database is to have a relatively small and manageable set of extreme storm sea states for comparison with wave forecast and hindcast products, model development and evaluation and satellite sensor calibration and validation. It has been suggested that an archive of storm surge events for similar purposes should also be considered. A draft proposal has been developed jointly by the ETWS and ETMC for discussion at their respective meetings in March 2007. The ETMC agreed with the development of the Database and recommendations by the ETWS-II (see ETWS-II Final Report). The ETMC invited its Members to seek National contributions to the database once established, and asked the Secretariat to draft a recommendation for JCOMM-III in this regard. Description of the JCOMM Extreme Wave database is provided in Annex X of the ETMC-II final report.
