A simple vertical thermal structure is proved applicable to the Pacific Ocean through correlation analysis test. Based on the Argo observations and WOA09(World Ocean Atlas 2009) climate data, we determine the parameters by the maximum angle method. Then in the Pacific Ocean, a three-dimensional subsurface temperature field whose spatial resolution is 1o×1o is inversed from high-resolution sea surface temperature. Compared with the observational temperature profiles, the inversion result is reliable and can be assimilated into the system of the ocean reanalysis as pseudo temperature observation. That will provide a strong theoretical basis and solid data base for realizing complementary advantages of the situ observation(such as Argo) and the satellite observation, which is conductive to construct the complete temperature analysis field.
