Meteorology · Observation — Reporting (VOS)
Ships participating in the Voluntary Observing Ship (VOS) scheme contribute to forecasting by:
- AReporting only once per voyage
- BRefusing to share any data
- CTransmitting routine weather observations from data-sparse ocean areas✓ Correct
- DSending observations only from port
Explanation
VOS ships take and transmit standard weather observations (pressure, wind, temperature, sea state, etc.) while underway, filling gaps over the oceans where few other observations exist. These reports feed numerical weather prediction and improve the marine forecasts mariners rely on.
