Spherical Triangulation gives identical results to Cowtan & Way

The Cowtan and Way temperature anomaly based on HadCRUT4.6 for 2017 has been released and it is 0.74C. This is uncannily similar to that calculated by Spherical Triangulation which is 0.73C. In fact both methods give essentially the same results … Continue reading

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

2017 is 3rd warmest year

The December 2017 data for ocean temperatures (HADSST3) and station data (CRUTEM4) were released today. I calculate that December (0.66C) was slightly cooler than November (0.67C) and that the final  2017 annual temperature anomaly was 0.73C. This makes 2017 the … Continue reading
