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…
