Nerem; et al. (2007). "Comment on 'Estimating future sea level change from past records' by Nils-Axel Mörner". Global and Planetary Change. 55 (4): 358–60. Bibcode:2007GPC....55..358N. doi:10.1016/j.gloplacha.2006.08.002. "Because the details of the analysis are not presented in his paper, we are left to speculate on how this result could have been obtained, based on our years of experience as members of the T/P and Jason-1 Science Working Team. Mörner was apparently oblivious to the corrections that must be made to the “raw" altimeter data to make correct use of the data.
As with any satellite data set, calibration and validation of the data must be performed after launch to determine if there are any instrumental errors, find the source of those errors, and evaluate their behavior over time. Satellite altimetry is somewhat unique in that many adjustments must be made to the raw range measurements to account for atmospheric delays (ionosphere, troposphere), ocean tides, variations in wave height (which can bias how the altimeter measures sea level), and a variety of other effects. In addition, the sea level measurements can be affected by the method used to process the altimeter waveforms, and by the techniques and data used to compute the orbit of the satellite. Early releases of the satellite Geophysical Data Records (GDRs) often contain errors in the raw measurements, the measurement corrections, and the orbit estimates that are later corrected through an on-going calibration/validation process defined by the T/P and Jason Science Working Team."
