CRUTEM4 is cooler than GHCN-V4

The October 2019 global temperature anomaly that I calculate based on the latest CRUTEM4 station data is 0.15C cooler than that using GHCN-V4 (0.79C asĀ  compared to 0.96C). The temperature series are calculated in exactly the same way and both … Continue reading

A comparison of HadCRUT4.6 using Icosahedral binning

The classic HadCRUT processing calculates average surface temperatures on a 5×5 grid in Latitude and Longitude. To calculate the global average a spatial weighting of cos(Lat) must be applied. The main advantage of using a more complex 3D Icosahedral grid … Continue reading

Icosahedral binning

A recent post by Nick Stokes has started me thinking again about the use of 3D Icosahedral binning of temperature data. Their major advantage is that all bins are of equal size on the earth’s surface thereby removing artificial spatial … Continue reading
