Raw Data and Full Ensemble Output (1880-2020) for "A NASA GISTEMPv4 Observational Uncertainty Ensemble"

Contains the Raw and Final data for "A NASA GISTEMPv4 Observational Uncertainty Ensemble" as accepted at JGR:Atmospheres (August 2024). 

FinalEnsembleOutput/ Contains the official GISTEMPv4 uncertainty ensemble from 1880-2020 with anomalies relative to a 1951-1980 climatology. The ensemble is organized into three subdirectories

FinalEnsembleOutput/FullEnsemble Contains a netCDF file [lon,lat,month] for each of the 200 members on a 2x2 grid.

FinalEnsembleOutput/GriddedSummary Contains netCDF files [lon,lat,month] of statistics summarizing the 200-member ensemble. The statistics contained are the ensemble mean, ensemble sd, quantiles, and sample size (can be less than 200 due to differences in the homogenization in data-sparse regions). The quantiles provided are (0.025, 0.05, 0.1, 0.25, 0.5, 0.75, 0.9, 0.95, 0.975).

FinalEnsembleOutput/KeySeries Contains 200-member ensembles of key, large scale time series at monthly resolution. Global, hemispheric, and zonal mean series are provided each for land, ocean, and combined (land and ocean) mean temeperature. Use this data when working with these series rather than calculating yourself from the full ensemble as the method for creating these series incoproates unertainty due to regions without coverage.

Raw/ Contains the raw, source data for the GISTEMP ensemble. This directory is not very large, but contains ~50k files as the GHCN product is distributed as an individual text file for every station in the record.
