Synoptic monthly gridded global and regional four?￠????dimensional World Ocean Database and Global Temperature and Salinity Profile Programme ( T , S , u , v ) fields with the optimal spectral decomposition and P?￠????vector methods

摘要

Synoptic monthly gridded (SMG) world ocean temperature ( T ) and salinity ( S ) fields with (1???°????????????1???°) horizontal resolution and 28 standard vertical levels from the ocean surface to 3000????m deep have been established from the observational ( T , S ) profiles from the NOAA National Centers for Environmental Information (NCEI) World Ocean Database (WOD) from January 1945 to December 2014 and the Global Temperature and Salinity Profile Programme (GTSPP) from January 1990 to December 2009 using the optimal spectral decomposition (OSD) method. The world ocean abstract geostrophic currents ( u , v ) are calculated from the 4D SMG?￠????WOD and SMG?￠????GTSPP ( T , S ) data using the P?￠????vector inverse method. The SMG?￠????WOD ( T , S , u , v ) and SMG?￠????GTSPP ( T , S , u , v ) fields with a higher horizontal resolution (0.25???°????????????0.25???°) have also been produced for the Mediterranean Sea, the Japan/East Sea, and the Gulf of Mexico.
