World Urban Morphological Parameters Open Dataset (WUMPOD)

WUMPOD is available with a spatial resolution of 500 m in Cloud Optimized GeoTIFF (COG) format and WRF-WPS format for easy access and utilization within the WRF modelling system. The COG format uses "Lempel–Ziv–Welch (LZW)" compression, overviews are embedded, and contains separate files of the following urban morphological parameters; MH (mean building height), STDH (standard deviation of building height), HGT (area weighted mean building height), LP (building plan area fraction), LB (building surface to plan area fraction), LF (frontal aspect ratio for cardinal directions of 0, 45, 90, and 135 degrees), LC (complete aspect ratio), H2W (height to width ratio), HI [0-75 m] (percentage distribution of building heights at every 5 m up to 75 m), Z0M, ZDM (Roughness length and displacement height according to Macdonald et al. (1998) for 0, 45, 90, and 135 directions), urban fraction (from WorldCover 2021) and missing building fraction. The WRF-WPS binary dataset contains additional variables, i.e., Z0S, ZDS (Roughness length and displacement height according to Grimmond and Oke (1999)), Z0R, and ZDR (Roughness length and displacement height according to Raupach (1994) for 0, 45, 90, and 135 directions), but it does not contain missing and urban fraction variables. Please read WRF-WPS readme file to use it in the WRF simulations. It is important to note that WRF-WPS binary, when uncompressed is approximately 630 GB. It is advised that user check disk space before uncompressing the file. The urban fraction in WRF-WPS format is available at https://zenodo.org/records/7298393WUMPOD数据集提供500米空间分辨率的云优化地理TIFF（Cloud Optimized GeoTIFF，COG）格式与WRF-WPS格式文件，便于在WRF数值模式系统中便捷访问与使用。COG格式采用Lempel–Ziv–Welch（LZW）压缩算法，内嵌影像金字塔，并包含以下独立的城市形态学参数文件：平均建筑高度（mean building height，MH）、建筑高度标准差（standard deviation of building height，STDH）、面积加权平均建筑高度（area weighted mean building height，HGT）、建筑基底面积占比（building plan area fraction，LP）、建筑表面积与基底面积之比（building surface to plan area fraction，LB）、0°、45°、90°与135°主方向下的正面迎风面积比（frontal aspect ratio for cardinal directions of 0, 45, 90, and 135 degrees，LF）、全向迎风面积比（complete aspect ratio，LC）、高宽比（height to width ratio，H2W）、0至75米区间内每5米间隔的建筑高度百分比分布（HI [0-75 m]）、Macdonald等人（1998）提出的对应0°、45°、90°与135°方向的空气动力学粗糙度长度与位移高度（Z0M、ZDM）、源自WorldCover 2021的城市地表占比（urban fraction）以及缺失建筑占比（missing building fraction）。 WRF-WPS二进制数据集额外包含以下变量：Grimmond与Oke（1999）提出的空气动力学粗糙度长度与位移高度（Z0S、ZDS），以及Raupach（1994）提出的对应0°、45°、90°与135°方向的空气动力学粗糙度长度与位移高度（Z0R、ZDR），但该数据集不包含缺失建筑占比与城市地表占比变量。使用该数据集开展WRF数值模拟前，请务必阅读WRF-WPS说明文档。 需要注意的是，未压缩的WRF-WPS二进制数据集体积约为630 GB，建议用户在解压前确认磁盘存储空间是否充足。 WRF-WPS格式下的城市地表占比数据集可于https://zenodo.org/records/7298393获取。
