The European Space Agency's Sentinel-3A Level-1 data products will soon be available from NASA's LAADS Distributed Active Archive Center (DAAC). On October 16, 2015, the United States of America (US) State Department and the European Commission (EC), signed a Cooperation Arrangement on Earth Observation data. Following this, the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) signed a Technical Operating Arrangement that provides access to data from the Sentinel satellites, the dedicated space component of the European Copernicus programme. NASA, working in conjunction with ESA, has implemented a Sentinel data mirror archive in the U.S. for re-use and re-dissemination of Sentinel products. The NASA mirror will increase distribution capacity, maximizing the benefits to Earth Science research and applications. As per the agreement, NASA will make the Sentinel core products available to users who register for Earth Observing System (EOS) Data and Information System (EOSDIS) user accounts, and who have agreed to the terms and conditions set by the European Union to access Sentinel data. NASA will provide all archived Sentinel data to all science data users without further access conditions or restrictions.

To access the NASA mirror site for Sentinel-3A Level-1 data, please visit the LAADS DAAC website For more information on the Copernicus Programme, please visit For more information on the Sentinel missions, please visit

The most recent information we received was that the standard products are expected sometime in January 2017.
