Global 1-km Sea Surface Temperature (G1SST)

A daily, global Sea Surface Temperature (SST) data set is produced at 1-km (also known as ultra-high resolution) by the JPL ROMS (Regional Ocean Modeling System) group. The input SST data sets are derived from the Global High-Resolution Sea Surface Temperature (SST) Pilot Project (GHRSST-PP).

Salinity Processes Upper Ocean

Sponsored by NASA, salinity Processes in the Upper Ocean Regional Study (SPURS) is exploring the salinity maximum region in the Atlantic Ocean using a plethora of oceanographic equipment and technology. The SPURS ocean modeling and forecasting system is developed to perform Observing System Simulation Experiments (OSSEs) prior to field campaigns, provide real-time forecast during field campaign, and produce reanalysis post field campaigns. The system is based on the community Regional Ocean Modeling System (ROMS), which is configured as a nested set of three spatial domains at horizontal resolutions of 9, 3 and 1 km and with 50 vertical levels. A multi-scale three-dimensional variational data assimilation (MS-3DVAR) scheme is used to assimilate observations from an array of satellites, autonomous vehicles, and other in-situ platforms.

California Coastal Ocean

The California Coastal Ocean (CA) data assimilation and forecasting system is used for developing the capability of assimilating satellite data along with shore-based radar and in-situ observations. The focus is placed on altimetry data, which continues to remain a challenge to be assimilated into coastal ocean models. This system is based on the Regional Ocean Modeling System (ROMS). The ROMS domain encompasses the entire California coastal region out to 1000 km off shore, with a horizontal resolution of 3 km and 40 vertical levels. A multi-scale three-dimensional variational data assimilation (MS-3DVAR) system is employed.
