Bob Tisdale shows us that GISS is once again, “way out there” in 2009 compared to other global temperature data sets. It is not surprising, we’ve come to expect it.

The annual NCDC Land+Sea Surface Temperature anomalies from 1982 to 2009, Figure 3, also do not show the record levels in 2009, but the NCDC does not infill with the 1200km smoothing like GISS.
GISS has used OI.v2 SST data since 1982. Figure 3 is an annual graph of SST anomalies for the Southern Hemisphere, and it illustrates that 2009 was not a record year for SST anomalies. That leaves the GISS land surface temperature anomaly data as the culprit.
Hadley Centre data is still not available for December, and they’ve been running late recently. The NCDC and GISS data through KNMI Climate Explorer data should be updated within the next few days, so we’ll be able to do some comparisons and try to determine which of the continents is responsible for the new record GISS Southern Hemisphere temperatures.
OI.v2 SST anomaly data is available through the NOAA NOMADS website:
The GISTEMP Southern Hemisphere Land Plus Surface Temperature data is available from GISS:
The NCDC Southern Hemisphere Land Plus Surface Temperature data is available here:
The UAH MSU TLT anomaly data was retrieved from the KNMI Climate Explorer:
