More ex-post "adjustments" to Satellite Sea-Level Altimetry

From a 2002 publication showing the Topex/Posiedon satellite altimetry sea level data for the eight years from 9/92-9/00, the global map shows stable to declining sea levels in most areas with the exception of the western Pacific, which is strongly influenced by periodic ENSO/El Nino/La Nina conditions.

The accompanying data below shows declining sea levels throughout most of the Pacific Ocean. The mean of the sea level changes (first number in each column) for each of the bands of the 3 major oceans shows a mean global sea level decrease of .4 mm/year. Yes, the bands for the 3 oceans are not the same size, but since the largest bands by far are in the Pacific Ocean and show the largest declines, the mean for the 3 oceans by area would therefore show an even greater decrease in mean sea level over the 8 year period. This is despite the fact that this period was also marked by the largest El Nino in the 20th century, which resulted in a large increase in the global mean.  

 

But that's not what the TOPEX/POSEIDON data show today, as somehow a global decrease in mean sea level evolved into a global increase of 3.1 mm/yr. This appears to be further confirmation of Dr. Nils Axel Morner's claim that the TOPEX satellite data was ex-post adjusted upward many years after the fact to show a false positive trend.  The data was further adjusted upward between 2005 and 2010 (almost 20 years after the start of the satellite record).
