Code Description
0 Temperature positive or zero
1 Temperature negative
TTT - Air temperature in whole degrees and tenths
e.g.
20.7°C is coded 207
0.3°C is coded 003
- Because auxiliary ships
are not equipped with tested instruments permitting the
determination of tenths of degrees of air temperature, a solidus (/) should be coded for the
tenths of degrees.
