Abstract

TOPEX/POSEIDON and JASON-1 sea level observations and Reynolds AVHRR sea surface temperature observations over the most recent 12 years have qualitatively been used to study global and regional correlations between long-term changes in sea level and sea surface temperature and to deduce the steric contribution to sea level change over this period. Consistent increases in both sea level and sea surface temperatures are found in most parts of the Atlantic Ocean over this period. In the Indian Ocean and particularly the Pacific Ocean, the trends in both sea level and temperature are still dominated by the large changes associated with the large El Ninõ Southern Oscillation in 1997-1998 (ENSO). Considerable effort have been put into the correction of the TOPEX and JASON-1 to account for possible offset between the missions. A mission offset of 154 mm have been applied along with adjustments to the TMR and JMR corrections.
