Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.
Suomi NPP data announcement
NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) platform measures the distribution of phytoplankton, a key indicator of ocean health.
PACE's primary instrument is the Ocean Color Instrument (OCI), a highly advanced optical spectrometer that measures properties of light over portions of the electromagnetic spectrum. OCI enables continuous measurement of light at finer wavelength resolution than previous NASA instruments, extending key system ocean color data records for climate studies.
