NCAR CESM Global Bias-Corrected CMIP5 Output to Support WRF/MPAS Research

This dataset includes global bias-corrected climate model output data from version 1 of NCAR's Community Earth System Model (CESM1) that participated in phase 5 of the Coupled Model Intercomparison Experiment (CMIP5), which supported the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5). The dataset contains all the variables needed for the initial and boundary conditions for simulations with the Weather Research and Forecasting model (WRF) or the Model for Prediction Across Scales (MPAS), provided in the Intermediate File Format specific to WRF and MPAS. The data are interpolated to 26 pressure levels and are provided in files at six hourly intervals. The variables have been bias-corrected using the European Centre for Medium-Range Weather Forecasts (ECMWF) Interim Reanalysis (ERA-Interim) fields for 1981-2005, following the method in Bruyere et al. (2014) [http://dx.doi.org/10.1007/s00382-013-2011-6]. Files are available for a 20th Century simulation (1951-2005) and three concomitant Representative Concentration Pathway (RCP) future scenarios (RCP4.5, RCP6.0 and RCP8.5) spanning 2006-2100.

NOTE: There are no bias-corrected data for RCP2.6, due to corrupted data caused by a model bug in CESM.

Note to Microsoft Windows users: The executable metgrid.exe, which is required to ingest this data into WPS/WRF, is not compatible with Windows and can only be run in a Linux environment. It is recommended, therefore, that this dataset be used in Linux environments only.

本数据集收录了全球气候模型校正偏差的输出数据，源自美国国家大气研究中心（NCAR）的社区地球系统模型（CESM1）的版本1，该模型参与了耦合模型互评实验（CMIP5）的第5阶段，并为政府间气候变化专门委员会第五次评估报告（IPCC AR5）提供了支持。数据集包含用于初始条件和边界条件模拟的气象研究预报模型（WRF）或尺度预测模型（MPAS）所需的所有变量，并以WRF和MPAS特定的中间文件格式提供。数据经过插值至26个压力层级，并以六小时间隔提供文件。变量已使用欧洲中期天气预报中心（ECMWF）的临时再分析（ERA-Interim）场进行偏差校正，遵循Bruyere等人（2014年）的方法[http://dx.doi.org/10.1007/s00382-013-2011-6]。文件包括20世纪模拟数据（1951-2005年）以及与之对应的三个代表性浓度路径（RCP4.5、RCP6.0和RCP8.5）的未来情景（2006-2100年）。

注意：由于CESM中的模型错误导致的损坏数据，RCP2.6没有校正偏差的数据。

针对微软Windows用户请注意：将数据导入WPS/WRF所需的可执行文件metgrid.exe与Windows不兼容，只能在Linux环境中运行。因此，建议仅在Linux环境中使用此数据集。
