AVHRR Global Mapped Eulerian and Lagrangian Oceanography and Ecology Variables Data, version 1

The ELOEV data suite packages a decade of global, multi-scale oceanographic context for ecology and movement studies, pairing Eulerian fields with Lagrangian metrics that describe transport and mixing. Typical use cases include marine predator habitat modeling, environmental selection studies, and process-to-pattern linkages in physical-biological oceanography.

Geophysical variables in this suite include:
