Regional climate simulations with the UCLouvain COSMO-CLM V. 6.0-CLM6 model

Project: CORDEX.be: COordinated Regional Climate Downscaling EXperiment and beyond - CORDEX.be provides a framework that aims to gather existing and ongoing Belgian research activities in the domain of climate modeling to create a coherent scientific basis for future climate services in Belgium. CORDEX.be is based on the international CORDEX (“COordinated Regional Climate Downscaling EXperiment”) project but the “.be” indicates it will go beyond for Belgium. The CORDEX.be project is a partnership of different research institutes and universities. In order to downscale the outcomes of the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5) to the specific requests for climate services at the Belgian scale, the following four targets are set: Target 1: Contribution to the CORDEX project Target 2: Beyond CORDEX: High-Resolution Limited Area Model runs Target 3: Beyond CORDEX: Local-Impact Models Target 4: Inferring the climate uncertainties to the Belgian level For more information, visit http://www.euro-cordex.be or e-mail [e-mail] Summary: Regional climate simulations with the COSMO-CLM V. 6.0-CLM6 model by UCLouvain.

Project: CORDEX.be：协调区域气候降尺度试验及延伸计划 —— CORDEX.be 旨在整合比利时当前及持续开展的气候建模领域研究活动，为比利时未来气候服务构建连贯的科学基础。该项目依托国际协调区域气候降尺度试验（COordinated Regional Climate Downscaling EXperiment, CORDEX）框架，但后缀".be"表明其针对比利时开展专属延伸研究。CORDEX.be 由多所科研机构与高校联合共建。为将政府间气候变化专门委员会第五次评估报告（IPCC AR5）的模拟结果降尺度至适配比利时尺度下气候服务的特定需求，项目设定了以下四大目标：
目标1：参与 CORDEX 国际项目
目标2：CORDEX 延伸计划：高分辨率有限区域模式模拟
目标3：CORDEX 延伸计划：局部影响模式研究
目标4：推导比利时尺度下的气候不确定性
