The mission of the Voluntary Observing Ship (VOS) project is two-fold: (1) to collect and disseminate critical real-time maritime weather observations through the recruitment and support of ships to fulfill National needs and International agreements supporting commerce, forecasts and warning programs, and the Safety Of Life At Sea (SOLAS) worldwide, and (2) to define the global climate and help measure extreme weather events, climate variability, and long-term climate changes.

VOS operates at no cost to the vessel, with communication charges, observing equipment and reporting supplies furnished by the National Weather Service.

To participate, contact a Port Meteorological Officer.
