藏东南高山环境综合观测研究站降雨雨滴谱不同季风时期特征观测数据集（2022-2023）

在二次科考项目和国家自然科学基金的依托下，在藏东南高山环境综合观测研究站架设了二维视频雨滴谱仪（2DVD），对降雨微物理特征进行观测。数据观测日期为2022年至2023年。基本观测要素为雨滴数浓度分布N（D），单位为mm-1m-3。时间分辨率为1分钟。本数据已经与观测站相近位置的雨量桶结果进行对比，结果吻合良好。在未来，可以通过粒子谱信息反演降雨量等，为天气气候模型中降雨的估算提供了良好的观测基础。

Supported by the Second Comprehensive Scientific Expedition Project and the National Natural Science Foundation of China, a two-dimensional video disdrometer (2DVD) was deployed at the Southeastern Tibet Alpine Environment Comprehensive Observation and Research Station to observe the microphysical characteristics of rainfall. The observation period spanned from 2022 to 2023. The core observed parameter is the raindrop number concentration distribution N(D), with the unit of mm⁻¹·m⁻³, and the temporal resolution is 1 minute. This dataset has been validated against measurements from a rain gauge near the observation station, exhibiting good consistency. In the future, rainfall amount and other relevant parameters can be retrieved from the particle size distribution information, providing a solid observational foundation for rainfall estimation in weather and climate models.
