- Abstract
Ocean heat storage is an essential component of the climate system and there is considerable interest in its accurate evaluation. There are a number of heat storage products produced by many different groups. These products are derived from Argo as well as other platforms, for example XBT and CTD, in the last decade. Here we compare two heat storage estimates for the North Atlantic 0-2000m from 10° to 70° N. One derived solely from Argo data whilst the other is derived from Argo and other platforms. It is found that there is a positive trend in heat storage over the period 1999- 2010. This trend is influenced by a strong air-sea interaction event in 2009-2010, and this reduces the upward trend 1999-2008 identified previously. Both data sets are consistent with each other for the layer 0-1000m on a timescale of beyond 1 yr. There are significant differences at sub-annual time scales and in the layer 1000-2000 m.
