Also contributing was the degree of weather station coverage.Data interpolation between stations contributed some uncertainty, as did the process of standardizing data that was collected with different methods at different points in history.

“Uncertainty is important to understand because we know that in the real world we don’t know everything perfectly,” said Gavin Schmidt, director of GISS and a co-author on the study.

“All science is based on knowing the limitations of the numbers that you come up with, and those uncertainties can determine whether what you’re seeing is a shift or a change that is actually important.” The study found that individual and systematic changes in measuring temperature over time were the most significant source of uncertainty.

Taken together, Schmidt said, the two studies help establish GISTEMP as a reliable index for current and future climate research.

“Each of those is a way in which you can try and provide evidence that what you’re doing is real,” Schmidt said."Normal" is defined as the average during a baseline period of 1951-80.NASA uses GISTEMP in its annual global temperature update, in partnership with the National Oceanic and Atmospheric Administration.Comparing two measurements that were similar but recorded in very different ways ensured that they were independent of each other, Schmidt said.One difference was that AIRS showed more warming in the northernmost latitudes.“We’re testing the robustness of the method itself, the robustness of the assumptions, and of the final result against a totally independent data set.” In all cases, he said, the resulting trends are more robust than what can be accounted for by any uncertainty in the data or methods.

The index includes land and sea surface temperature data back to 1880, and today incorporates measurements from 6,300 weather stations, research stations, ships and buoys around the world.Previously, GISTEMP provided an estimate of uncertainty accounting for the spatial gaps between weather stations.Like other surface temperature records, GISTEMP estimates the temperatures between weather stations using data from the closest stations, a process called interpolation.Quantifying the statistical uncertainty present in those estimates helped researchers to be confident that the interpolation was accurate.
