Potential impacts are uncertain due to modeling differences between ESMs, internal variability stemming from the chaos of the earth system, and differences in the historical reference datasets used to bias-corrected and downscale ESM output. The Bias-Corrected and Downscaled Massive Ensemble (BCD-ME) is a multi-model large ensemble of over 1,400 projections of daily mean and maximum temperature. The BCD-ME samples model and internal uncertainty with up to 86 runs from 12 Large Ensembles (LEs; and single runs from 10 further ESMs) and uncertainty in the reference dataset by using 4 different reanalysis products to bias-correct and downscale output. Output is organized by Global Warming Levels (GWL), accounting for differences between forcing scenarios and ESM climate sensitivities, or by 20-year chunks. The ensemble contains 20-year daily time series for each GWL on a uniform 1-degree grid, bias-corrected using Quantile Delta Mapping, statistics of 20-year time series for each GWL on a uniform 0.25-degree grid, downscaled using Quantile-Preserving Localized Analog Downscaling. The BCD-ME also includes a set of 20-year daily time series of model output run on SSP3-7.0, but organized by model calendar year, for comparison with GWL-based data. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png Zarr dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CLIMATE MODELS > CLIMATE MODELS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-08-19 revision 24.6 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > MAXIMUM/MINIMUM TEMPERATURE > 24 HOUR MAXIMUM TEMPERATURE U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-08-19 revision 24.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1906 2090 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 20268986.122 https://gdex.ucar.edu/datasets/d164444/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d164444/dataaccess/ https Data Access Related Link download none asNeeded
