The twice-yearly update of the Copernicus marine product INSITU_GLO_PHY_TS_DISCRETE_MY_013_001 (hereafter referred to as the CORA dataset) implies performing a delayed-time mode validation of the temperature and salinity in-situ profiles. One of the most crucial tests in this validation process involves comparing the new profiles to a reference field of minimum and maximum observed temperature and salinity (DM MinMax field). This test has proven to be highly accurate for delayed-mode validation. The DM MinMax field is refined after each major release of the dataset.
