Calculating global temperature anomalies using three new methods.

Abstract Deriving global temperatures anomalies involves the surface averaging of normalized ocean and station temperature data that are inhomogeneously distributed in both space and time. Different groups have adopted different averaging schemes to deal with this problem. For example GISS … Continue reading

How to normalise temperature anomalies

Update 2/7/17: I used the wrong GISS data (land only) in the comparison as pointed out by @cce! Agreement now is reasonably good for all temperature series. This is my crib sheet for comparing temperature anomalies across ground and satellite … Continue reading

Nights warm faster

NOAA’s Global Historical Climatology Network (GHCN) publishes 3 different monthly temperature sets for each of the ~7000 weather stations. 1) Average Temperatures 2) Minimum Temperatures 3) Maximum Temperatures. Seasonal variations are averaged out over a 30 year normalisation period to … Continue reading
