Upper Ocean Heat Content
Anomaly Data Plots
These figures show the current state of the ocean heat
content anomaly. Historical data are from XBTs, CTDs, moorings, and
other sources. A preliminary ad-hoc fall rate correction has been
applied
to the XBT data in an attempt to correct for biases between XBT data
and more
accurate CTD data. Recent estimates are based primarily on Argo profiling CTD float data.
Satellite altimeter data from Aviso
are used to estimate sampling errors.

Standard sampling error for
globally
averaged OHCA of the upper 750 m. This quantity was computed using sea
surface height anomaly maps from altimeter data and the historical
sampling patterns for in situ profile data in each year as discussed in
Lyman et al. 2006.
Sampling errors are not the entire error budget. Instrument
biases and errors in the climatology are among the other errors that
must be considered in a complete error budget.
