October temperatures rise 0.18C

Posted on November 16, 2019 by Clive Best

October saw a large increase of 0.18C in the global average temperature (anomaly) since September. These results use a spherical triangulation of land (GHCN-V4) and ocean (HadSST3) temperature data with a baseline of 1961-1990. The methodology is described in this … Continue reading →

A comparison of HadCRUT4.6 using Icosahedral binning

Posted on November 1, 2019 by Clive Best

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

Posted on October 26, 2019 by Clive Best

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 →
