COSMO-REA6 Regional Reanalysis

The high-resolution reanalysis system COSMO-REA6 has been developed based on the NWP model COSMO in a cooperation between Hans-Ertel-Centre for Weather Research (HErZ) and the German Meteorological Service (DWD). Initially, COSMO-REA6 was produced for 1995-2014 at University of Bonn (https://reanalysis.meteo.uni-bonn.de/), Hans-Ertel-Centre for Weather Research (HErZ), see https://www.herz.uni-bonn.de/wordpress/. It was extended from 2015 onwards by DWD. The DWD provides selected COSMO-REA6 output under https://opendata.dwd.de/climate_environment/REA/. The data provided via ESGF and WDCC underwent an additional CMIP/CORDEX-like standardisation ("CMORisation"), conducted in a cooperation between DKRZ and DWD within the OcMOD (Observations closer to MOdel Data) NFDI4Earth Pilot, and also comprises a different selection of parameters that was determined through a community survey (https://c6dreq.dkrz.de/files/ocmod_dreq.php). The CMORisation efforts within the NFDI4Earth Pilot were funded by the Deutsche Forschungsgemeinschaft (DFG - project number: 460036893).基于数值天气预报模型COSMO，COSMO-REA6高分辨率再分析系统在汉斯-埃特尔气象研究中心（HErZ）与德国气象局（DWD）的合作下得以开发。最初，COSMO-REA6由波恩大学（https://reanalysis.meteo.uni-bonn.de/）、汉斯-埃特尔气象研究中心（HErZ）于1995-2014年间制作，详细信息请见https://www.herz.uni-bonn.de/wordpress/。自2015年起，德国气象局（DWD）对其进行了扩展。 德国气象局（DWD）在https://opendata.dwd.de/climate_environment/REA/上提供了选定的COSMO-REA6输出数据。通过ESGF和WDCC提供的数据经过了一个额外的CMIP/CORDEX类似的标准化过程（CMOR化），该过程在OcMOD（Observations closer to MOdel Data）NFDI4Earth试点项目中由DKRZ和DWD合作完成，并且包含了通过社区调查确定的参数选择（https://c6dreq.dkrz.de/files/ocmod_dreq.php）。NFDI4Earth试点项目中的CMOR化工作由德国研究联合会（DFG）资助（项目编号：460036893）。
