Upper Ocean Mooring Data Repository - The Subduction Experiment
Meteorological Instrumentation
Data Sources
The source of data for each meteorological variable at each site is presented in time-line form.
Sample Rate
The sampling interval for the VAWRs was 15 min, whereas that for the IMET systems was 1 min. Numerical weather prediction (NWP) products were available only every 6 h. Data were either averaged (IMET) or interpolated (NWP) as necessary to produce files with a 15 min sample interval.Buoy Types
Sensor heights are different for the two types of buoys used on Subduction moorings. At some sites, the buoy type changed after the first deployment due to floatation problems with the Toroid buoys. VAWR Serial Numbers and Buoy Types| Deployment | NE | C | SW | SE | NW |
|---|---|---|---|---|---|
| 1 | 704 Discus | 722 Discus | 720 Toroid | 721 Toroid | 121 Toroid |
| 2 | 380 Discus | 712 Discus | 713 Toroid | 707 Discus | 717 Discus |
| 3 | 721 Discus | 121 Discus | 720 Toroid | 704 Discus | 722 Discus |
