The auxiliary ship's code does not include the wet-bulb temperature, dew-point, characteristic
of barometric tendency, change of atmospheric pressure, wave data, sea surface temperature
and cloud data. Furthermore because auxiliary ships are not equipped with tested instruments
permitting the determination of tenths of degrees of air temperature and/or tenths of hPa of
pressure, tenths are not reported. Course and speed must be included only when reporting ice
accretion and/or ice.
