CORDEX simulation (evaluation) on 12.5 km grid over Europe based on RegCM4-2 (v1: MIT convection scheme) forced by ERA-Interim (EUR-11)

Project: CORDEX dynamical downscaling data sets based on CMIP5 forcing - CORDEX (http://wcrp-cordex.ipsl.jussieu.fr) is a WCRP initiative to coordinate the downscaling of CMIP5 simulation results produced in support of the IPCC/AR5. About 30 institutes worldwide contributed to the CORDEX data base with more than 20 RCMs in various configurations and versions. CORDEX defined 13 domains (http://wcrp-cordex.ipsl.jussieu.fr/images/pdf/cordex_regions.pdf) with acronyms AFR(Africa), EUR(Europe), ARC(Arctic), ANT(Antarctica), MED(Mediterranean), SAM(South America), CAM(Central America), NAM(North America), WAS(South Asia), EAS(East Asia), CAS(Central Asia), AUS(Austral-Asia), ARB(Mediterranean-North Africa). The priority domain is the African continent. The data are requested to be generated on model grids with an approximate grid cell distance of 50/25/12 km (acronyms -44/-22/-11), preferably on rotated regular latitude-longitude grids. A subset of the requested data is provided on 0.5/0.25/0.125° regular latitude/longitude grids in project CORDEX_DDS-CMIP5_lat-lon-grid. RCM evaluation with the ERA-Interim re-analyses data (1989-2008) is mandatory. Besides, downscaling of historical experiments (1950-2005) and of climate change scenarios RCP 4.5 and 8.5 is requested. Many groups also used RCP 2.6 climate projections. For more details see http://is-enes-data.github.io/cordex_archive_specifications.pdf . A list of the variables requested by CORDEX can be downloaded from this project (CORDEX_variables_requirement_table.pdf). Not all variables will be provided by all RCMs though. Note that 3 and 6 hourly data are also available, however, only at the modelling centres on request. Summary: This data of the project CORDEX includes CORDEX experiments for the domain for Europe in high resolution (EUR-11) based on DHMZ's RegCM4-2 model. Each file contains a single variable in the format NetCDF-4 compressed with CF standard names (CF-1.4). The data are provided on the model computational (native) grid. Information on additional project naming conventions is specified in the project description. The data include several daily, monthly and seasonal variables from the DHMZ-RegCM4-2 simulation forced by the ERA-Interim reanalysis. Data format follows CORDEX data protocol.

项目：基于CMIP5强迫场的协调区域气候降尺度试验（CORDEX）动力降尺度数据集。协调区域气候降尺度试验（CORDEX，http://wcrp-cordex.ipsl.jussieu.fr）是世界气候研究计划（WCRP）发起的一项倡议，旨在协调针对支撑政府间气候变化专门委员会第五次评估报告（IPCC/AR5）所生成的CMIP5模拟结果的降尺度工作。全球约30家科研机构为CORDEX数据库贡献了超过20套不同配置与版本的区域气候模式（RCMs）。CORDEX划定了13个模拟区域，各区域缩写及对应范围如下：AFR（非洲）、EUR（欧洲）、ARC（北极）、ANT（南极洲）、MED（地中海区域）、SAM（南美洲）、CAM（中美洲）、NAM（北美洲）、WAS（南亚）、EAS（东亚）、CAS（中亚）、AUS（澳亚区域）、ARB（地中海-北非区域），详细区域说明可参见http://wcrp-cordex.ipsl.jussieu.fr/images/pdf/cordex_regions.pdf。优先研究区域为非洲大陆。数据集需基于模式网格生成，网格分辨率近似为50/25/12 km（对应缩写为-44/-22/-11），优先采用旋转规则经纬网格。在CORDEX_DDS-CMIP5_lat-lon-grid项目中，提供了部分需求数据集，其采用0.5/0.25/0.125°的规则经纬网格存储。需采用ERA-Interim再分析资料（1989-2008年）对区域气候模式进行验证，此项为强制要求。此外，还需开展历史试验（1950-2005年）以及气候变化情景RCP 4.5和RCP 8.5的降尺度工作。不少研究团队还采用了RCP 2.6气候预估情景。更多详细信息可参见http://is-enes-data.github.io/cordex_archive_specifications.pdf。CORDEX所需的变量列表可从本项目中下载，文件名为CORDEX_variables_requirement_table.pdf。不过并非所有区域气候模式都会提供全部所需变量。请注意，每3小时和每6小时的数据集也可获取，但仅可应要求向模式研发中心申请。项目概况：本项目CORDEX的数据集包含基于DHMZ的RegCM4-2模式构建的高分辨率欧洲区域（EUR-11）CORDEX试验数据。每个文件仅包含单个变量，采用遵循CF标准命名规范（CF-1.4）的压缩NetCDF-4格式存储。数据集采用模式计算（原生）网格存储。更多项目命名规范的相关信息可参见项目说明文档。本数据集包含由ERA-Interim再分析资料强迫的DHMZ-RegCM4-2模拟结果中的多个日、月及季节尺度变量。数据格式符合CORDEX数据协议规范。若需获取该模拟的相关数据，请联系[e-mail]。
