Arpa Piemonte – 3R Weather – Rain last 3h in real time

Flood level measurements recorded in real time by the stations of the regional weather network managed by Arpa Piemonte and automatically validated. The data is processed to obtain the cumulative rain in the last 3h.The data are updated every 20 minutes with a delay of about one hour and the times are expressed in the local time system.The stations of the network are divided into four basic types: Rain station — the minimum instrumental equipment consists of a flood gauge to which other meteorological sensors are associated locally; Weather station — complete stations have a rainometer, thermometer, hygrometer, speed meter and wind direction, and locally barometer and radiometer; Nivometric Station — In high mountain environment, stations add to the normal weather configuration, snow height sensors and snow cover temperature. The nivological data collected in this way complement those collected by the manual nivometric network, providing indications relating to unmanned areas and of particular interest; Hydrometric station — the minimum equipment consists of an ultrasonic hydrometer to which a pressure hydrometer and various meteopluviometer sensors are associated locally.本数据集包含皮埃蒙特地区环境防护局（Arpa Piemonte）管理的区域气象网络站点实时采集、并经自动校验的水位测量数据。经处理后可获取近3小时累积降雨量。数据每20分钟更新一次，存在约1小时的延迟，时间采用本地时区表示。该网络的站点分为四类基础类型：雨量站（Rain station）——其最低配置包含一台水位计，本地可关联其他气象传感器；气象站（Weather station）——完备型站点搭载雨量计、温度计、湿度计、风速计与风向传感器，本地还可配置气压计与辐射计；雪情监测站（Nivometric Station）——针对高海拔山地环境，此类站点在常规气象配置基础上，增设雪深传感器与积雪温度传感器；以此类方式采集的雪情数据可补充人工雪情监测网络的采集内容，为无人区及重点关注区域提供监测信息；水文站（Hydrometric station）——其最低配置包含一台超声水位计，本地可关联压力水位计与多类雨量气象传感器。
