Highlights
This graph plots the average of ten different global temperature datasets. To create this graph, Robert Way had to track down a number of different temperature series. There were your classic “rock star” datasets – NASA GISS, NOAA and HadCRUT. The other favourites, although not going back as far as the thermometer records, are the satellite records UAH and RSS.
But another great addition are a number of other “reanalysis products”. These are datasets that use a wide range of sources to reconstruct temperature. This includes thermometers, radiosondes, satellites, buoys and ship measurements. This way, they’re able to create temperature records covering the entire globe, even Arctic regions that other datasets such as UAH, RSS and HadCRUT fail to cover.
