Description
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:
vars_aqua:
• Zeu_lee – Euphotic depth, Lee algorithm (m)
• chl_ocx – Chlorophyll concentration, OC3 algorithm (mg m⁻³)
• kd_490 – Diffuse attenuation coefficient at 490 nm, KD2 algorithm (m⁻¹)
• par – Photosynthetically Available Radiation (Einstein m⁻² day⁻¹)
• poc – Particulate Organic Carbon (mg m⁻³)
• sst – Sea Surface Temperature (°C)
vars_orbview-2:
• Zeu_lee – Euphotic depth, Lee algorithm (m)
• chl_ocx – Chlorophyll concentration, OC3 algorithm (mg m⁻³)

• par – Photosynthetically Available Radiation (Einstein m⁻² day⁻¹)
• poc – Particulate Organic Carbon (mg m⁻³)
vars_noaa poes:
• sst – Sea Surface Temperature (°C)
vars_models:

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
