      Three months of local sea level derived from reflected GNSS signals

      J. S. Löfgren, R. Haas, H.-G. Scherneck and M. S. Bos

      Version of Record online: 8 NOV 2011 | DOI: 10.1029/2011RS004693

      Key Points

      • Standard geodetic GNSS receivers can measure reflections from the sea surface
      • Possible to monitor the sea-level using regular single difference processing
      • From the GNSS-based tide gauge results we find significant ocean tidal signals

      Improving the accuracy of sea surface salinity retrieval using GNSS-R data to correct the sea state effect

      E. Valencia, A. Camps, N. Rodriguez-Alvarez, I. Ramos-Perez, X. Bosch-Lluis and H. Park

      Version of Record online: 24 SEP 2011 | DOI: 10.1029/2011RS004688

      Key Points

      • Use GNSS-R measurements to directly describe the sea state
      • From GNSS-R data correct ocean L-band brightness temperature measurements
      • Use corrected brightness temperature to improve sea surface salinity retrieval
