Subtitle: “0.45 deg C per Century warming in Hadley Centre sea surface temperature (SST) data for both hemispheres compared to Reynolds (NOAA) SST data 1982-2008”
I have been surprised at the magnitude of the hemispheric differences between HadSST2 and Reynolds V2 SST data, equivalent to 0.45 degrees C per Century.
In 2006 I found errors in Hadley Centre SST data in previous work around New Zealand, for example.
In August 2006 I posted: “What integrity is there in global SST trends ?”
If anyone has the computing ability and time to produce some global maps of monthly differences between HadSST2 and Reynolds V2 SST data, please let me know. This would allow homing in exactly where the discrepancies are located and assessing the validity of both series against other data.
