Sensitivity studies on rain heterogeneity in Hamburg city centre using the obstacle-resolving model MITRAS

This experiment contains sensitivity test results (Ferner et al. 2023) of 11 simulations with the microscale, obstacle-resolving model MITRAS v 3.1 (Salim et al., 2018; Schluenzen et al., 2018) for a domain of 1.6 x 1.8 km² around Hamburg City Hall in Hamburg. The domain contains various street configurations, open spaces, water surfaces, orography and building heights. The simulations were performed with different initial wind speeds, rain amounts, wind directions, and domain configurations. The simulations cover 1:40 hours, starting at 7:30 LST (LST refers to Local Solar Time), with a temporal resolution of 10, 1 or 5 minutes. This experiment contains a selection of output variables, control variables are not included.

The file names of the data sets are composed as follows.
{precipitation}_{intensity}_{windspeed}_ {intensity}_{winddirection}_{value}_{case ID}.nc

There are 3 intensities: low, medium, high
Associated values are these:
pr_low = 0.5 mm, pr_medium =0.9 mm, pr_high = 1.7 mm (after 10 minutes)
ff_low = 2 m/s, ff_medium = 4 m/s, ff_high = 4 m/s

Example:

本实验收录了针对位于汉堡市政厅周边1.6 x 1.8 km²区域内的微尺度、障碍物解析模型MITRAS v 3.1（Salim et al., 2018; Schluenzen et al., 2018）进行的11次模拟的敏感性测试结果（Ferner et al. 2023）。模拟区域涵盖了多样化的街道布局、开阔空间、水面、地形以及建筑高度。模拟实验在多种初始风速、降水量、风向和区域配置下进行。模拟时长为1:40小时，起始时间为7:30地方平太阳时（LST），时间分辨率为10、1或5分钟。本实验选取了部分输出变量，控制变量未包含在内。

数据集的文件名组成如下：{降水量}_{强度}_{风速}_{强度}_{风向}_{值}_{案例ID}.nc

存在三种强度级别：低、中、高。

相应的数值如下：
pr_low = 0.5 mm，pr_medium = 0.9 mm，pr_high = 1.7 mm（10分钟后）
ff_low = 2 m/s，ff_medium = 4 m/s，ff_high = 4 m/s
