Appears In:	Context Diagram: MeteorologicalAerodromeObservation

An aggregation of sea state conditions typically reported together at an aerodrome. This includes information on sea-surface temperature and either the state of the sea or significant wave height from aeronautical meteorological stations established on offshore structures in support of helicopter operations

Notes:

The sea-surface temperature observed by aeronautical meteorological stations established on offshore structures in support of helicopter operations. The term sea surface temperature is generally meant to be representative of the upper few meters of the ocean as opposed to the skin temperature, which is the temperature of the upper few centimeters.
