Sentinel-6B
(Jason-CS-B)
Sentinel-6B aims to continue high-precision ocean altimetry measurements in the 2020–2030 time-frame using two successive, identical satellites, Jason-CS-A and Jason-CS-B. A secondary objective of Sentinel-6 is to collect high-resolution vertical profiles of temperature, using the GNSS Radio-Occultation sounding technique, to assess temperature changes in the troposphere and stratosphere and to support Numerical Weather Prediction.
