The SDC_GLO_CLIM_TS_V2 product is an improved version of SDC_GLO_CLIM_TS_V1 and contains two different monthly climatologies for temperature and salinity from the World Ocean Database 2018 (WOD-18). Along with the basic quality control flags from the WOD-18, an additional quality control named Nonlinear Quality Control (NQC) is applied. The first climatology, V2_1, considers temperature and salinity profiles from Conductivity Depth Temperature (CTD), Ocean station data (OSD) and Moored buoy data (MRB) along with Profiling Floats (PFL) from 1900 to 2017. The second climatology, V2_2, utilizes only PFL data from 2003 to 2017.

V2_1 considers 44 layers from surface to 6000 m while V2_2 only 34 from 0 to 2000 m. The gridded fields are computed using DIVAnd (Data Interpolating Variational Analysis) version 2.3.1. Basic statistics for differences between the WOD gridded fields, so-called World Ocean Atlas 2018 (WOA-18) and the SDC_GLO analyses are computed and the estimates are found to be consistent.
