Abstract
An analysis of the steric and ocean mass components of sea level shows that the sea level rise budget for the period January 2004 to December 2007 can be closed. Using corrected and verified Jason-1 and Envisat altimetry observations of total sea level, upper ocean steric sea level from the Argo array, and ocean mass variations inferred from GRACE gravity mission observations, we find that the sum of steric sea level and the ocean mass component has a trend of 1.5 +/- 1.0 mm/a over the period, in agreement with the total sea level rise observed by either Jason-1 (2.4 +/- 1.1 mm/a) or Envisat (2.7 +/- 1.5 mm/a) within a 95\% confidence interval.
