CMIP5 Model-Data Comparison: Satellite-Era Sea Surface Temperature Anomalies

Guest post b y Bob Tisdale As we’ve seen in numerous model-data comparisons, there are few similarities between modeled and observed surface temperatures and precipitation.  See here, here, here, here, and here for examples.  We’ve compared satellite-era sea surface temperature to model outputs in past posts (examples here, here and here), but we used model…
