2 | NASA Satellite Altimetry for Measuring Sea Surface Height | This timeline shows the history of NASA satellites, past and present, used to measure the height of the sea surface. The data collected allow for the determination of global mean sea level. Plus the future missions with launch dates are given. | https://sealevel.jpl.nasa.gov/system/resources/detail_files/1169_AltimeterMissions2021-browse.jpg | https://sealevel.jpl.nasa.gov/resources/1169/altimeter-mission-series/ | NASA Altimeter Mission Series | title | ||||||||||||
