PAR005 Optical disdrometer data at De Zweth

<strong>Description:</strong> In-situ measurements of raindrop size distributions, fall velocities, drop number concentrations and surface rain rates recorded by an OTT Parsivel2 disdrometer named "PAR005" in De Zweth, The Netherlands. Situated approximately 7 km to the North West of Rotterdam, and 4 km South East of Delft campus, Zweth is a small town along the Schie river, at the intersection of the historical areas of Delfland and Schieland. The same site also features a micro-rain radar "MRR004_DeZweth" (since February 2022), replaced by "MRR006_DeZweth" (since August 2022) and a Davis weather station "Davis003_DeZweth" (since May 2023). All sensors are placed on top of an air quality monitoring container belonging to TNO, at a height of approx. 4 meters.<br><strong>Format:</strong> Each NetCDF file covers a full month of observations. The temporal resolution is 1 minute. Data are provided "as is", without any post-processing. The NetCDF files contain all relevant information about all the variables, attributes and units. The global attributes of the NetCDF files contain important information about the type of sensor, logging software, project contributors and history of the dataset. If a monthly file is missing, no data are available for this month.<br><strong>Relevance:</strong> Optical disdrometer data are useful for studying the type, dynamics and microphysics of precipitation from the perspective of a fixed observer on the ground. The data can be used to help calibrate weather radars, improve quantitative precipitation estimates, calculate the absorption/attenuation/propagation of electromagnetic signals through the atmosphere, and quantify important physical quantities such as liquid water content, rain amount, intensity and kinetic energy.<br><strong>Note:</strong> This dataset is updated approximately every 3 months. Please reach out to the authors if you wish to access the most recent data.<br><strong>Known issues:</strong>Due to a sensor malfunction, the recorded temperature values between November 2023 and December 15, 2024 cannot be trusted.

<strong>描述：</strong> 荷兰德兹韦特（De Zweth）地区由名为"PAR005"的OTT Parsivel2雨滴谱仪（disdrometer）记录的雨滴尺寸分布、下落速度、雨滴数浓度及地面雨强的原位测量数据。德兹韦特是斯海尔河畔的小镇，位于鹿特丹西北约7公里、代尔夫特校区东南4公里处，地处德尔夫兰（Delfland）与斯海尔兰（Schieland）历史区域的交汇处。同一站点还配备了一台微雨雷达（micro-rain radar）"MRR004_DeZweth"（自2022年2月起），后于2022年8月更换为"MRR006_DeZweth"；此外有一台戴维斯气象站（Davis weather station）"Davis003_DeZweth"（自2023年5月起）。所有传感器均安装在荷兰应用科学研究组织（TNO）的空气质量监测集装箱顶部，高度约4米。<br><strong>格式：</strong> 每个NetCDF文件涵盖一整月的观测记录，时间分辨率为1分钟。数据以"原样"形式提供，未经过任何后处理。NetCDF文件包含所有变量、属性及单位的相关信息；其全局属性记录了传感器类型、日志软件、项目贡献者及数据集历史等重要内容。若某月度文件缺失，则该月无可用数据。<br><strong>相关性：</strong> 光学雨滴谱仪（optical disdrometer）数据可从地面固定观测者视角研究降水的类型、动力学特征及微物理过程。该数据可助力气象雷达校准、改进定量降水估计、计算电磁信号在大气中的吸收/衰减/传播特性，并量化液态水含量、降雨量、雨强及动能等关键物理量。<br><strong>说明：</strong> 本数据集约每3个月更新一次。如需获取最新数据，请联系作者。<br><strong>已知问题：</strong> 由于传感器故障，2023年11月至2024年12月15日期间记录的温度值不可信。
