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…

Accuracy, Precision, and One Watt per Square Metre

Guest Post by Willis Eschenbach I’ve been investigating one of my favorite datasets in the last few days, the CERES satellite-based top-of-atmosphere (TOA) radiation dataset. In particular, I’ve taken month-by-month global and hemispheric averages of the data. The dataset consists of observations of three variables—downwelling solar radiation, upwelling longwave (infrared) radiation, and upwelling shortwave radiation…

Forcing The Ocean To Confess

Guest Post by Willis Eschenbach According to the current climate paradigm, if the forcing (total downwelling energy) increases, a combination of two things happens. Some of the additional incoming energy (forcing) goes into heating the surface, and some goes into heating the ocean. Lately there’s been much furor about what the Levitus ocean data says…

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…

By Land and By Sea

Guest post by Willis Eschenbach Bob Tisdale has discussed a variety of issues with the hemispheric and basis-by-basin Levitus summary of the ARGO data in his excellent post here on WUWT. I wanted to take a larger look at at the global ocean data, to provide it with some context. After following a variety of…
