Abstract

A new methodology is proposed for computing the city-descriptive parameters for the TERRA_URB scheme in the COSMO model. It is based on the GIS analysis of OpenStreetMap data, Sentinel-2 satellite images, and global land cover data. A set of parameters is obtained for Moscow megacity on a grid with the spacing of 500 m. The dataset is promising for high-resolution numerical weather prediction within the COSMO-Ru system and for urban climate research.

COSMO模型框架中莫斯科大城市高分辨率数字天气预报的城市描述参数计算

摘要

提出了一种新的方法来计算COSMO模型中TERRA_URB方案的城市描述参数。它基于OpenStreetMap数据，Sentinel-2卫星图像和全球土地覆盖数据的GIS分析。对于莫斯科特大城市，在间距为500 m的网格上获得了一组参数。该数据集有望用于COSMO-Ru系统内的高分辨率数值天气预报以及城市气候研究。
