Kriging biases in global temperature data

I have made a new calculation of global temperatures using 7300 NOAA/NCDC V3c station data combined with HadSST3 ocean temperature. For the ocean data I use cell locations only where measurements exist for a given month.  I then make a (lat,lon) triangulation … Continue reading →

Temperature data averaged 3 ways

How should you calculate annual global temperature data? We start with Hadcrut4.5 gridded monthly data defined on a 5×5 degree grid and then form the global area weighted average in 3 different ways. Integrate the annual anomaly  over month,lat & … Continue reading →

Land Temperature Anomalies.

This post studies the methodologies and corrections that are applied to derive global land temperature anomalies. All the major groups involved use the same core station data but apply different methodologies and corrections to the raw data. Although overall results are … Continue reading →
