CROCUS Tipping Bucket Rain Gauge Data at Argonne National Laboratory Prairie Site

The Tipping Bucket Rain Gauge (TBRG) dataset contains data from both the Nova-Lynx 12 inch TBRG and the Met One 8-inch TBRG. The dataset contains one minute measurements for precipitation accumulation measured in that timeframe from both instruments. Each TBRG was equipped with heaters for all-season measurements. These data are helpful for identifying periods of drought, potential flooding, and general input for water budgets. TBRGs can be used to validate optical rain gauge data and disdrometer data collected during the CROCUS project. Data were collected at the Argonne Testbed for Multiscale Observational Science (ATMOS), a 20-acre prairie site at Argonne National Laboratory in Lemont, Illinois. The data is presented as daily NetCDF (.nc) files, each containing approximately 24 hours of observations. Files follow the naming convention of: the project (CROCUS), location (atmos), instrument name (tbrg), data level (raw, a1), and date (year, month, day). The NetCDF format can be accessed using common scientific software such as Python using xarray, netCDF4 or act-doe.

本翻斗式雨量计（Tipping Bucket Rain Gauge, TBRG）数据集包含Nova-Lynx 12英寸TBRG与Met One 8英寸TBRG的观测数据。数据集收录了两台仪器的分钟级降水累积量观测数据，每一条记录对应1分钟时长内的降水累积量。每台TBRG均配备加热装置，可支持全季节野外观测。该数据集可用于识别干旱时段、潜在洪涝风险，同时可为水量平衡研究提供基础输入数据。TBRG观测数据还可用于验证CROCUS项目期间采集的光学雨量计与雨滴谱仪观测数据。观测数据采集于伊利诺伊州莱蒙特市阿贡国家实验室内的阿贡多尺度观测科学试验场（Argonne Testbed for Multiscale Observational Science, ATMOS），该站点为占地20英亩的草原观测场。数据集以每日NetCDF（.nc）文件形式存储，每个文件包含约24小时的观测数据。文件命名遵循如下规范：依次由项目名称（CROCUS）、站点标识（atmos）、仪器名称（tbrg）、数据层级（raw为原始数据、a1为一级处理数据）以及日期（年、月、日）组成。NetCDF格式数据可通过常用科学软件读取，例如Python生态下的xarray、netCDF4及act-doe库。
