Argo, Temperature, and OHC

Guest Post by Willis Eschenbach I’ve been thinking about the Argo floats and the data they’ve collected. There are about 4,000 Argo floats in the ocean. Most of the time they are asleep, a thousand metres below the surface. Every 10 days they wake up and slowly rise to the surface, taking temperature measurements as…

New CERES Data and Ocean Heat Content

Guest Post by Willis Eschenbach We have gotten three more years of data for the CERES dataset, which is good, more data is always welcome. However, one of the sad things about the CERES dataset is that we can’t use it for net top-of-atmosphere (TOA) radiation trends. Net TOA radiation is what comes in (downwelling…

Why Reanalysis Data Isn’t …

Guest Post by Willis Eschenbach I was reading through the recent Trenberth paper on ocean heat content that’s been discussed at various locations around the web. It’s called “Distinctive climate signals in reanalysis of global ocean heat content”,  paywalled, of course. [UPDATE: my thanks to Nick Stokes for locating the paper here.] Among the “distinctive climate…

The Layers of Meaning in Levitus

Guest Post by Willis Eschenbach There have been a lot of electrons sacrificed on the altar of the discussion of the Levitus ocean heat content data. The oddity seems to be that the deep ocean is gaining heat faster than the upper ocean. Here’s a typical graphic showing the issue: Figure 1. Changes in the…
