Global Surface Warming Hiatus Analysis Data

These data were used to conduct the study of the global surface warming hiatus, an apparent decrease in the upward trend of global surface temperatures since 1998. The data are from 1880-2014 for global land, ocean, and land-ocean areas. The data include both gridded, time series, uncorrected and corrected data. An additional analysis specific to the Arctic is included. There is an Old Analysis and New Analysis; the old being the current operational version running at NCEI at the time. The New analysis uses ERSSTv4 and land surface air temperature data from the ISTI Databank with adjustments applied using the algorithm operational for GHCN-M v3. There are files in the Old Analysis and New Analysis containing the global 5X5 degree gridded anomalies. Anomalies are based on the climatology from 1971 to 2000.
