This utility/program helps with collecting metadata for WMO Publication No. 47. WMO
Publication No. 47 (Pub47), the International List of Selected, Supplementary and Auxiliary
Ships, contains details about the names, call signs, ship layout, types of instrumentation and
methods of observation used on VOS ships. It relies on the regular submission of metadata
from National Meteorological Services operating VOS programmes, nominally on a quarterly
basis.
