Results of QC

A total of 274 profiles (211628 data, reported by BATHY or TESAC) were received from the MAERSK LOME.
The results of JMA quality control are as follows.
  • Grounded test
  • Error data: 210 of 211628

  • Position on land test
  • On land: 0 of 274

    Invalid position: 0 of 274

  • Regional range test
  • Error data (low): 0 of 211628

    Error data (high): 18 of 211628

  • Gradient test
  • Error data: 255 of 211628

Summary of QC

  • QC detected some unnatural profiles shown in 'Results of QC'.
  • There are large differences at depths of between 100 and 300 m in the seas south of 5°N. The observation data shows sharper thermocline better than the assimilation data.
