I am working on the annual numbers, and hope to do a special post tomorrow.

 

 

Background

For anyone not familiar with all this, UAH and RSS are the two satellite datasets, that measure temperatures in the lower troposphere, from the surface up to about 8000 metres. The HADCRUT and GISS datasets measure surface temperatures.

All temperatures are presented as anomalies, i.e the difference, measured against a baseline that is different across all four sets.

The baselines used are:

 

RSS – 1979-98

UAH – 1981-2010

HADCRUT – 1961-90

GISS – 1951-80

 

HADCRUT is maintained the UK Met Office’s Hadley Centre in conjunction with the Climatic Research Unit at the University of East Anglia.

GISS is run by the Goddard Institute for Space Studies at NASA.

UAH is the University of Alabama in Huntsville, and their dataset is part of an ongoing joint operation with NOAA and NASA.

RSS is a scientific research company, Remote Sensing Systems.

    Uh oh

    Looks like RSS is showing a doward trend of about 0.1-0.2 /C.

    Quick, someone “adjust” the data!

    Oops, sorry, that should be “0.1-0.2 /D”
