收藏CatMeows
该数据集包含440个声音样本,由21只属于两个品种(缅因州库恩猫和欧洲短毛猫)的猫在三种不同情境下发出的喵声组成。这些情境包括刷毛、在陌生环境中隔离和等待食物。每个声音文件都遵循特定的命名约定,包含猫的唯一ID、品种、性别、猫主人的唯一ID、录音场次和发声计数。此外,还有一个额外的zip文件,包含被排除的录音(非喵声)和未剪辑的连续发声序列。

全国 1∶200 000 数字地质图(公开版)空间数据库
As the only one of its kind, China National Digital Geological Map (Public Version at 1∶200 000 scale) Spatial Database (CNDGM-PVSD) is based on China' s former nationwide measured results of regional geological survey at 1∶200 000 scale, and is also one of the nationwide basic geosciences spatial databases jointly accomplished by multiple organizations of China. Spatially, it embraces 1 163 geological map-sheets (at scale 1: 200 000) in both formats of MapGIS and ArcGIS, covering 72% of China's whole territory with a total data volume of 90 GB. Its main sources is from 1∶200 000 regional geological survey reports, geological maps, and mineral resources maps with an original time span from mid-1950s to early 1990s. Approved by the State's related agencies, it meets all the related technical qualification requirements and standards issued by China Geological Survey in data integrity, logic consistency, location acc racy, attribution fineness, and collation precision, and is hence of excellent and reliable quality. The CNDGM-PVSD is an important component of China' s national spatial database categories, serving as a spatial digital platform for the information construction of the State's national economy, and providing informationbackbones to the national and provincial economic planning, geohazard monitoring, geological survey, mineral resources exploration as well as macro decision-making.

中国逐日降水数据集(1961-2022,0.1°/0.25°/0.5°)
CHM_PRE数据集基于中国境内及周边1961至今共2839个站点的日降水观测,在传统的“降水背景场 + 降水比值场”的数据集构建思路上,尝试应用月值降水约束和地形特征校正,并依据中国范围内约4万个高密度站点2015–2019年的日降水量插值后数据进行精度评价。经评估认为,CHM_PRE可以较好的表征降水的空间变异性,其日值时间序列与高密度站点日值降水观测结果之间的相关系数中位数为0.78,均方根误差中位数为8.8 mm/d,KGE值中位数为0.69,与目前常用的降水数据集(CGDPA、CN05.1、CMA V2.0)有很好的一致性。 数据集的时间范围为1961年至今,空间分辨率为0.1°、0.25°和0.5°,经纬度范围为18°N–54°N, 72°E–136°E。
