'''Short description:'''

The global ocean objective analysis (gridded) fields of temperature and salinity are produced from the in situ profiles available in the multiparameter near–real-time in situ product INSITU_GLO_PHYBGCWAV_DISCRETE_MYNRT_013_030, with the exception of moorings, thermosalinographs and surface drifters. The objective analysis is based on the ISAS method (Gaillard et al. 2009), a statistical estimation approach that enables the mapping of ocean in situ profiles onto three-dimensional gridded fields.

The resulting gridded product has a spatial resolution of 0.5° in latitude and 0.5° in longitude at the equator and includes 187 vertical levels. It provides monthly temperature and salinity fields centered the 15th of the month, with the analysis of the previous month delivered on the 8th of each month.

A monthly file (data file) gathering the observed profiles used to calculate the analysis, which are interpolated on the vertical grid, is also provided.

The product covers a two-year sliding time window. Older data are available in the corresponding delayed-mode product, INSITU_GLO_PHY_TS_OA_MY_013_052.
