sequenceNumber=1
Notes: The sea-surface temperature observed by aeronautical meteorological stations established on offshore structures in support of helicopter operations.<br/><br/>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.<br/><br/>Temperatures shall be reported in degrees Celsius ("Cel").<br/><br/>ICAO Annex 3 / WMO No. 49-2:<br/>Section 4.8.1.5a<br/>
