Synoptic Monthly Gridded WOD Absolute Geostrophic Velocity (SMG-WOD-V) (January 1945 - December 2014) with the P-Vector Method (NCEI Accession 0146195)

The SMG-WOD-V dataset comprises synoptic monthly global gridded fields of absolute geostrophic velocity inverted from the synoptic monthly gridded WOD temperature and salinity fields (NCEI Accession 0140938) using the P-vector method. It provides monthly varying velocity field that is dynamically compatible to the SMG-WOD (T, S) fields. The SMG-WOD-V has the same spatial resolution and temporal variation as the SMG-WOD (T, S) fields, but does not cover the equatorial zone (5oS – 5oN) due to the geostrophic balance being the theoretical basis for the P-vector inverse method.
