Correlation Between NCEP/NCAR Re-analysis and Other Global Temperature Anomaly Data

Guest Post By Walter Dnes On his website, Nick Stokes has set up an interesting global temperature anomaly visualization, based on NCEP/NCAR re-analysis data. The dry technical details are listed in this blog post. Based on his explanation, I’ve been able to closely duplicate his work to within +/-0.003 Kelvin degree, using different tools. This post…

The Warmer The Icier

Guest Post by Willis Eschenbach A WUWT commenter emailed me with a curious claim. I have described various emergent phenomena that regulate the surface temperature. These operate on time scales ranging from minutes to hours (e.g. dust devils, thunderstorms) to multi-decadal (e.g. Atlantic Multidecadal Oscillation, Pacific Decadal Oscillation). He suggested that there is also a…

Is NOAA’s Hiatus Gone? (Now Includes May Data)

Guest Post by Werner Brozek, Edited by Just The Facts: The above are plots of what the slopes NOAA’s surface temperature anomalies look like for the three intervals 1975 to 2000; 1950 to 2000; and 2000 to 2015. The top one is before adjustments and the bottom one is after adjustments, seemingly in an attempt…

Average TOA Radiation Imbalance 2000 2014

Temperature and TOA Forcing

Guest Post by Willis Eschenbach I’ve been thinking about temperature and top-of-atmosphere (TOA) forcing. TOA forcing is the imbalance between the TOA upwelling and downwelling radiation. The CERES satellite dataset contains observations of the TOA radiation imbalance on a gridcell-by-gridcell basis. It is calculated as the downwelling solar radiation for that month by gridcell, minus…
