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
The Copernicus Sentinel-3 series of satellites measure Earth’s oceans, land, ice, and atmosphere to monitor and understand large-scale global dynamics. It provides essential information in near real-time for ocean and weather forecasting.
Sentinel-3B, which launched on April 25, 2018, was operated by the European Space Operations Centre (ESA) during the Commissioning Phase and EUMETSAT from the routine operations phase onwards.
Type
Earth Observation Satellites
Data Center
OB.DAAC
Launch
April 25, 2018
Objective
Measure sea surface topography, sea and land surface temperature, and ocean and land surface color
Sentinel-3B is a collaboration among the European Space Operations Centre (ESA) and EUMETSAT. ESA has agreed with NASA, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Geological Survey (USGS) to make data available to them from the European Sentinel satellites.
