GHCN August 2018 temp = 0.69C

Global temperatures for August 2018 were 0.69C based on merging GHCNV3 and HadSST3, and using spherical triangulation. The baseline for temperature anomalies is 1961-1990. The annual average so far (8 months) for 2018 is 0.66C. 2018 is continuing a post … Continue reading

July’s Hadcrut4.6(3D) = 0.65C

My preferred method for calculating the global average temperature anomaly¬† for HADCRUT4.6 is by triangulating the measurements over the surface of a sphere. This gives almost identical results to those of Cowtan & Way but is a far simpler and … Continue reading

HADCRUT4.6 for June 2018

The CRUTEM4.6 weather station data for June 2018 has just been published, which when combined with the HadSST3 sea surface temperature data forms the global average – HadCRUT4.6. The traditional method for calculating this is by binning all the station … Continue reading
