In Situ Profiles
- T from TAO and PIRATA moored buoys
- T and S from RAMA moored buoys
- T from eXpendable Bathythermographs (XBTs)
- T and S from Argo profiling floats and CTDs
- Synthetic salinity profiles are also assimilated for the TAO and PIRATA buoys and XBTs
Satellite
- Sea Level Anomalies (SLA) from Topex, Jason-1, and Jason-2 altimeter data
- Sea Surface Temperature (SST) from Reynolds and CMIP5
Climatology
- Randomly chosen profiles of T and S from Levitus
- Sea Surface Salinity (SSS) from Levitus
