- All times are in UTC
- The decimal day is a zero-based value. Noon January 1 UTC is 0.5, not 1.5.
This is the best convention when dealing with data that may cross over

decimal days will just keep increasing past the end of the year)

The CODAS values for time and position are those at the end
of the ensemble. Other scalars associated with a given ensemble
(temperature, heading) are averaged.
- Pitch and roll (if available) are recorded but not used in the
