OCEAN MODELING AND DATA ASSIMILATION SYSTEM: Observing System

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
