But concerning the ocean heat uptake, have you some confidence in altimetric sea level measurement?
Willis et al. (2004) used satellite altimetric height combined with about 900,000 in situ ocean temperature profiles to produce global estimates of upper - ocean (upper 750 m) heat content on interannual timescales from mid-1993 to 2002 (see Figure 4 - 3).
Even when there doesn't happen to be an overpass at surge time, the statistics of sea level that we got from more than 20 years of repeated altimetric observations in the area can still be combined with data from nearby tide gauges to improve the forecasts of the expected surge.»
The global increase in ocean heat content during the period 1993 to 2003 in two ocean models constrained by assimilating altimetric sea level and other observations (Carton et al., 2005; Köhl et al., 2006) is considerably larger than these observational estimates.
The MDT for a different time period P can be easily deduced using altimetric Sea Level Anomalies referenced to the 1993 - 1999 period with: MDTP = MDT93 - 99 + P.
Since altimetric data and global tidal hydrodynamic solutions have reached a centimetric resolution, a connection between tides and climate is now conceivable.
The global increase in ocean heat content during the period 1993 to 2003 in two ocean models constrained by assimilating altimetric sea level and other observations (Carton et al., 2005; Köhl et al., 2006) is considerably larger than these observational estimates.
Temperature changes over the upper 500 m account for only part of the altimetric sea level rise.
Effects of this order are readily visible in gravimetric and altimetric satellite records.
Since 1992, global mean sea level can be computed at 10 - day intervals by averaging the altimetric measurements from the TOPEX / Poseidon (T / P) and Jason satellites over the area of coverage (66 ° S to 66 ° N)(Nerem and Mitchum, 2001).
