In this article we outline the model development planned within the joint project Model-based city planning and application in climate change (MOSAIK). The MOSAIK project is funded by the German Federal Ministry of Education and Research (BMBF) within the framework Urban Climate Under Change ([UC]2) since 2016. The aim of MOSAIK is to develop a highly-efficient, modern, and high-resolution urban climate model that allows to be applied for building-resolving simulations of large cities such as Berlin (Germany). The new urban climate model will be based on the well-established large-eddy simulation code PALM, which already has numerous features related to this goal, such as an option for prescribing Cartesian obstacles. In this article we will outline those components that will be added or modified in the framework of MOSAIK. Moreover, we will discuss the everlasting issue of acquisition of suitable geographical information as input data and the underlying requirements from the model’s perspective.

基于 PALM 模型开发新的城市气候模型 – 项目概述、计划工作和初步成果

在本文中，我们概述了在气候变化中基于模型的城市规划和应用 (MOSAIK) 联合项目中计划的模型开发。MOSAIK 项目由德国联邦教育和研究部 (BMBF) 在 2016 年以来在变化中的城市气候 ([UC]2) 框架内资助。 MOSAIK 的目标是开发一个高效、现代、高分辨率城市气候模型，可应用于柏林（德国）等大城市的建筑分辨率模拟。新的城市气候模型将基于完善的大涡模拟代码 PALM，该代码已经具有许多与此目标相关的功能，例如用于指定笛卡尔障碍的选项。在本文中，我们将概述将在 MOSAIK 框架中添加或修改的那些组件。而且，
