Objectively mapped velocity data at 1000 dbar derived from trajectories of Argo floats

http://www.jamstec.go.jp/ARGO/argo_web/G-YoMaHa/index_e.html

We mapped the drift data from the Argo floats, YoMaHa'07 , 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.
