Abstract
System and method for maintaining the observed vertical structure of ocean temperature and salinity in data assimilation systems that otherwise would produce overly smoothed ocean vertical structure. The present embodiment uses a multi-layer least squares minimization technique in which the ocean is split into layers with fundamentally different vertical gradients, and the dynamic ocean layers are constrained by the observed vertical gradients of the layer itself.
Claims20
A computer-implemented method for constructing synthetic ocean profiles comprising the steps of:
- automatically identifying ocean property data related to an ocean location;
- automatically splitting the ocean into a plurality of layers throughout the depth of the ocean at the ocean location;
- identifying an interface between each of the plurality of layers, each of the interfaces occurring at an interface ocean depth;
- automatically computing constraints based on the vertical gradient of the ocean property data and other constraints in each of the plurality of layers;
- automatically applying the constraints in each of the plurality of layers to produce layer profiles;
- automatically combining the layered profiles to construct the synthetic ocean profile;
- and
- automatically providing the synthetic ocean profiles to computer readable media.
