How does satellite altimetry work
WebThis article & comments at WUWT have a good discussion of how adjustments have increased rate of sea-level rise reportedly “measured” by satellite altimetry.(h/t Steve Case [here & here])Another example illustrating the malleability of the satellite altimetry data is a widely-hyped 2024 paper by U. Colorado's Dr. Steve Nerem et al, which claimed to have … WebSatellite altimetry is all about timing. Sea-surface height can be measured by the time it takes for radar pulses to hit the ocean surface and bounce back to the spacecraft. Laser …
