Position on land test

On land: 0 of 151

Invalid position: 0 of 151

Regional range test

Error data (low): 0 of 117366

Error data (high): 0 of 117366

Gradient test

Error data: 20 of 117366

Summary of QC

QC detected some unnatural profiles shown in 'Results of QC'.
At the depths between 50 m and 150 m in the seas around 3°S, there were differences above 2°C between observation data and the results of assimilation. The observation data shows sharper thermocline than the assimilation data.
