Baltimore Ecosystem Study: Precipitation measurements at eight stations

Abstract: Rain depth is collected using model 6011-A tipping bucket rain gauges manufactured by All Weather Inc. (formerly Qualimetrics). Two raingauges (RG1 and RG2) are installed at each of eight stations. Each rain gauge tip represents a depth of 0.01 inches of rainfall. Data are recorded by a data logger at the station and telemetered hourly to UMBC, where the data are stored in a data base. The rain gauges are not heated and therefore snow and ice storms are removed from the published record. The QA/QC procedure applied to the raw data includes removal of false tips and snow/ice events, accumulating tip data to a time series in inches/min, applying a laboratory-based calibration curve to the data, and converting corrected data to a one-minute time series in units of mm/min for publication.摘要：本数据集采用All Weather公司（前身为Qualimetrics）生产的6011-A型翻斗式雨量计采集降雨量数据。8个监测站点各安装两台雨量计（RG1与RG2），每一次翻斗翻转对应0.01英寸的降雨量。站点处的数据记录仪负责记录数据，并每小时将数据遥传至UMBC，存储于数据库中。该雨量计未配备加热装置，因此公开数据中已剔除暴雪与冰暴事件。针对原始数据开展的质量保证与质量控制（QA/QC）流程包括：剔除虚假翻斗计数与冰雪事件，将翻斗计数数据整合为以英寸/分钟为单位的时间序列，采用实验室校准曲线对数据进行校正，并将校正后的数据转换为以毫米/分钟为单位的1分钟时间序列以供发布。
