Monthly Centering and Climate Sensitivity

In our recent discussion of Dessler v Spencer, UC raised monthly centering as an issue in respect to the regressions of TOA flux against temperature. Monthly centering is standard practice in this branch of climate science (e.g. Forster and Gregory 2006, Dessler 2010), where it is done without any commentary or justification. But such centering […]

The Dessler (2011) Regression

Dessler (2011) reported the following: A related point made by both LC11 and SB11 is that regressions of TOA flux or its components vs. ΔTs will not yield an accurate estimate of the climate sensitivity λ or the cloud feedback. This conclusion, however, relies on their particular values for σ(ΔFocean) and σ(ΔRcloud). Using a more […]

Troy: Dessler(2010) “artifact of combining two flux calculations”

Troy_CA has another excellent contribution to the continuing analysis of Dessler 2010 and Dessler 2011 (h/t Mosher for alerting me) CA readers are aware that the sign of the regression coefficient from Dessler 2010 is reversed when CERES clear sky is used in combination with CERES all sky, instead of replacing CERES clear sky with […]

More Hypocrisy from the Team

Bishop Hill draws attention to the publication of Trenberth’s comment on Spencer and Braswell 2011 in Remote Sensing. Unlike Trenberth’s presentation to the American Meteorological Society earlier this year (see here here here, Trenberth et al 2011 was not plagiarized. The review process for Trenberth was, shall we say, totally different than the review process […]

More on Dessler 2010

CERES data, as retrieved in its original state (see here) provides all-sky and clear-sky time series. Dessler 2010 made the curious decision to combine ERA clear-sky with CERES all-sky to get a CLD forcing series. This obviously invites the question about the impact of using CERES clear-sky in combination with CERES all-sky to calculate the […]

The Stone in Trenberth’s Shoe

Like most of us, I’ve been a bit taken aback by the ritual seppuku of young academic Wolfgang Wagner, formerly editor of Remote Sensing, for the temerity of casting a shadow across the path of climate capo Kevin Trenberth. It appears that Wagner’s self-immolation has only partly appeased Trenberth, who, like an Oriental despot, remains […]
