    • Sentinel-6 NASA/JPL GNSS-RO Near-Real-Time Level 1B V1 (S6A_RO_1B_NRT_NC__) at GES DISC

    Metadata Updated: August 29, 2025

    This dataset provides the L1B Global Navigation Satellite System (GNSS) Radio-Occultation (RO) Near-Real-Time (NRT) retrieval generated by NASA's Jet Propulsion Laboratory (JPL) from Sentinel-6A Michael Freilich. The main retrieval variable in this dataset is bending angle. Each granule is for one RO and represented by the nominal geodetic reference location for the occultation, where the latitude and longitude are associated with the moment when the line-of-sight connecting the receiver and transmitter satellites just touches the reference ellipsoid. Sentinel 6 is a collaborative mission between NASA's JPL and European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), with participation from European Space Agency (ESA), the USA's National Oceanic and Atmospheric Administration (NOAA), and Centre National d’Études Spatiales (CNES) of France. These organizations will deliver an operational mission as part of a two-satellite European Copernicus/Sentinel program. The Sentinel-6A Michael Freilich Jason-CS (Sentinel-6A) was launched in November 21, 2020. One objective of Sentinel 6 is to collect high-resolution vertical profiles of temperature and humidity, using GNSS RO sounding technique, to assess temperature and humidity changes in the troposphere and stratosphere and to support numerical weather prediction.
