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

July temperature up 0.1C

The global averaged surface temperature for July 2019 was 0.75C using my spherical triangulation method merging GHCNV3 with HadSST3. This is an increase of 0.13C since June. This is a large monthly rise but still in line with past monthly … Continue reading
