The North West Pacific SWOT Cal/Val site contains active eddies and internal gravity waves which provide a suitable calibration dynamic background field.
This Cal/Val system has placed four mooring arrays within the SWOT swath in the Subtropical Countercurrent (STCC) region. The moorings are equipped with temperature sensors (SBE56), CTDs (SBE37), and ADCP, collecting hydrographic data and velocity data of the upper ocean. They are located at the vertices and center of a triangle, with the vertices about 7.5 km to the center.
This system will allow a better understanding of the role of submesoscale processes in a highly stratified current system and will give insight into the current ocean state in this region.
