Abstract:

This dataset includes climate model output data from NCAR's Community Earth System Model (CESM) CMIP 5 runs, configured as CCSM4 (CAM4), with output fields for the 3-D global atmosphere at six hourly intervals. A basic set of parameters is provided on 26 model hybrid level surfaces: specific humidity, temperature, wind components, and geopotential height to support regional modeling studies. Additional parameters are provided on single level grids to support analysis studies including surface temperature. Data are available in yearly time-series parameter archive files, and monthly synoptic time archive files. An interface is provided to give users the option to select parameter, temporal, and spatial subsets from the monthly synoptic time archive files. The data are a single 20th Century (1950-2005) simulation and three concomitant Representative Concentration Pathway (RCP) future scenarios spanning 2005-2100. These computer runs were completed in 2011.

Users needing for WRF boundary conditions are recommended to use the bias corrected version of this dataset found in RDA dataset ds316.1, NCAR CESM Global Bias-corrected CMIP5 Output to Support WRF/MPAS Research.

NOTE: All RCP2.6 data has been removed due to corrupted data caused by a model bug.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
