RAPID Original Data Format
--------------------------

The RAPID array at 26°N produces a range of observational and derived products:

- 1D time series of AMOC transport
- Time series profiles of temperature, salinity, and velocity at specific locations (moorings)
- Gridded sections of hydrographic and velocity fields
- Layer transport estimates based on defined vertical boundaries
- Streamfunction evaluations in depth or density space
