Description
The Net Primary Production Carbon, Absorption, Fluorescence Euphotic-resolving (NPP_CAFE) data suite includes estimates of oceanic net primary production derived from ocean-color observations using the Carbon, Absorption, Fluorescence Euphotic-resolving (CAFE) model. The CAFE model combines satellite-derived optical properties with phytoplankton physiology, light availability, and photosynthetic processes to estimate the rate of carbon fixation by marine phytoplankton. NPP_CAFE products are used to assess ocean productivity, ecosystem health, carbon cycling, biological responses to environmental variability, and the role of phytoplankton in the global carbon cycle.
Geophysical variables in this suite include:
- npp_cafe — Net primary productivity of biomass expressed as carbon (mg m⁻² day⁻¹)

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.
