Total precipitation data at the Poker Flat Research Range (PFRR) in 2022

At the Poker Flat Research Range of the University of Alaska Fairbanks, the Geonor Inc. T-200BMD precipitation gauge is installed to observe total precipitation. The T-200BMD is a vibrating wire precipitation gauge specifically designed for accurate total precipitation measurement in all weather conditions. The data represents cumulative values recorded every 30 minutes, with the final time of the accumulation period indicated in the TimeStamp. Missing data is represented by -9999 and has a Flag value of 2. A Flag value of 0 indicates reliable data. A Flag value of 1 means the data is slightly less reliable but still usable. The gauge is equipped with a protective casing and features a 200 cm2 inlet that complies with WMO standards. Total precipitation is measured using vibrating wire load sensors. The device, along with a wind shield, is installed on a pedestal. Antifreeze is used to melt solid precipitation within the container, eliminating the need for electrical heating and reducing potential errors. Additionally, a thin oil layer is applied to minimize evaporation.在阿拉斯加费尔班克斯大学扑克平地研究场（Poker Flat Research Range），布设了吉诺公司（Geonor Inc.）的T-200BMD型雨量计（T-200BMD precipitation gauge）以监测总降水量。该T-200BMD为振弦式雨量计，专为全天气条件下的高精度总降水量测量设计。 本数据集包含每30分钟记录的累积降水量数据，累积周期的终止时刻将在时间戳（TimeStamp）中予以标注。缺失数据以-9999表示，其数据标记（Flag）值为2；数据标记值为0代表数据可靠；标记值为1则表示数据可信度略低但仍可正常使用。 该雨量计配备防护外壳，拥有符合世界气象组织（WMO）标准的200平方厘米进雨口，采用振弦式荷载传感器实现总降水量测量。设备与防风罩一同安装在基座之上。为融化容器内的固态降水，装置使用防冻液替代电加热方案，有效降低了潜在测量误差；此外，还通过在容器内涂布薄层油膜以减少降水蒸发损耗。
