G-YoMaHa (Objectively mapped velocity at 1000 dbar derived from trajectories of Argo floats)

We mapped the drift data from the Argo floats, YoMaHa'07 (version September 2012), at the depth of 1000 dbar (approximately 1000 m) on a 1 degree grid.
The mapping method is statistically optimal. The mapped velocity field satisfies the geostrophic balance and the horizontal boundary condition of no flow through the boundary.
