Data Quality Assurance Protocol (Absolute Rule #1)● Passed Automated & Physical Screening
Every observation and grid point served by OceanEmbed is checked against strict oceanographic validity criteria. In-situ profiles originate directly from Global Argo GDAC NetCDF files. Reanalysis fields originate from Copernicus GLORYS12V1. Points located on land or lacking verified marine data return an explicit no_data status—never fabricated or smoothly hallucinated numbers.
Dataset Screening & Sensor Calibration Audits
| OBSERVATION NETWORK | QC FILTER LEVEL | REJECTION CRITERIA | OUTLIER HANDLING | COMPLIANCE |
|---|---|---|---|---|
| Argo Robotic CTD Float Network | GDAC RTQC & DMQC Stage 2 | Flag 3 (Bad) and Flag 4 (Suspect) | Pruned strictly; zero interpolation | PASSED (Rule #1) |
| Copernicus GLORYS12V1 Reanalysis | Reduced-Order Kalman 3D-VAR | Bathymetric masking & unphysical spikes | Explicit land-sea mask return | PASSED (Rule #1) |
| OSTIA Satellite SST Foundation | Optimal Interpolation L4 | Diurnal warm layer contamination | Skin error standard deviation tracking | PASSED (Rule #1) |
| CCMP Satellite Wind Vectors | Variational Analysis Method (VAM) | Rain flag contamination & coastal backscatter | Assimilated ECMWF boundary constraints | PASSED (Rule #1) |
