Fields
<1>
C = temperature
<2>
Calculated “relative” wind chill temperature, degrees Celsius, to the
nearest 0.1 degree
<3>
C = degrees C
<4>
WCHR (ID indicating relative wind chill)
<5>
C = temperature
<6>
Calculated “theoretical” wind chill temperature, degrees Celsius, to the
nearest 0.1 degree
<7>
C = degrees C
<8>
WCHT (ID indicating theoretical wind chill)
<9>
A = angular displacement
<10>
Pitch: oscillation of vessel about its latitudinal axis. Bow moving up is
positive. Value reported to the nearest 0.1 degree.
<11>
D = degrees
<12>
PTCH (ID indicating pitch of vessel)
<13>
A = angular displacement
<14>
Roll: oscillation of vessel about its longitudinal axis. Roll to the
starboard is positive. Value reported to the nearest 0.1 degree.
<15>
D = degrees
<16>
ROLL (ID indicating roll of vessel)
