Long-Range CODAR
Real-Time Data
The raw surface current is the unprocessed
data measured by CODAR. Therefore these velocity fields are the summation
of all sources of current, including tides and wind.
This vector field represents the component of the raw velocity that is caused by tidal forcing. Using a least squares approximation, the following constituents
were used to calculate the tidal velocity fields:
- Half a Lunar Day (Period = 12.42 Hours)
- Half a Solar Day (Period = 12.00 Hours)
- A Lunar Day (Period = 25.82 Hours)
- Luni-Solar (Period = 23.93 Hours)
- Larger Lunar Elliptic (Period = 12.66 Hours)
The detided vector field contains all the surface currents shown in the raw velocity field with the exception of the tidal currents. Using the above periods, a predicted tide is calculated and then subtracted
from the raw data field.
The Averaged vector field is a 36 hour average of the detided field.
The inertial vector field is calculated using a least squares fit to the detided data over the most recent 36 hours.
