Monthly climatology of the upper Southern Ocean south of 60S

Climatology of in-situ temperature and practical salinity south of 60S, from 10 to 380m, resolution 0.5x0.5 degrees.

The maps are based on Argo, shipboard and seals CTD data. The raw profiles are decomposed in modes using a functional PCA (Pauthenet et al, 2019). The resulting principal components horizontal fields are interpolated for each months on a regular 0.5x0.5 degree grid, with the optimal interpolation of Schmidtko et al. (2013). Then climatological profiles are reconstructed at each grid points.
