A look at HadCRUT4.6 Icosahedral binning

This post uses the underlying HadCRUT4.6 data to examine the small differences in global temperatures resulting from the choice of spatial binning. HadCRUT4.6¬† is based on 7680 monthly CRUTEM4 station data and HADSST3 Sea Surface temperature data. Temperature anomalies are … Continue reading

HadCRUT 4.6 temperatures compared

CRUTEM station data for October was released a few days ago. So I can now make a direct comparison of different surface averaging methodologies. The calculated October temperature anomaly for the 3 different spatial averages, as¬†described previously are the following … Continue reading

Icosahedral Binning

The earth is roughly a sphere so an unbiased method to bin surface temperature data is to treat the surface itself in 3D. Ideally each bin should cover exactly the same surface area, so that the global average is simply … Continue reading
