CROCUS Low Cost All-in-One Weather Station AMB-001 Data Argonne National Laboratory Prairie Site

The Ambient Weather WS-2902D (AMB) is a low cost weather station that has become very useful for filling data gaps in harder to deploy locations. These low cost weather stations collect 13 second data, which is averaged to a five minute data output available to users through an API key. The data files contain measurements for precipitation, temperature, wind chill/heat index, relative humidity, dew point, UV index, solar radiation, wind speed, wind direction, wind gust, and with an external particulate matter 2.5 (PM 2.5) sensor. Having all of these measurements in one condense system allows for fast deploying and dense network capabilities. Three of the AMB weather stations were deployed at the Argonne Testbed for Multiscale Observational Science (ATMOS), a 20-acre prairie site at Argonne National Laboratory in Lemont, Illinois. The instruments are denoted by their three digit identifier (CMS-AMB-xxx) format. 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 (CMS-AMB-001), 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.

安比气象（Ambient Weather）WS-2902D（AMB）是一款低成本气象站，在填补部署难度较高区域的数据空白方面极具应用价值。该类低成本气象站以13秒为间隔采集数据，并将其平均处理为5分钟级数据输出，用户可通过API密钥获取该数据。数据文件涵盖降水、气温、风寒/热指数、相对湿度、露点、紫外线指数、太阳辐射、风速、风向、阵风强度，以及外接颗粒物2.5（PM 2.5）传感器的观测数据。将上述所有观测指标集成于一套紧凑系统中，可实现快速部署并支持构建高密度观测网络。共有3台AMB气象站部署于多尺度观测科学试验场（Argonne Testbed for Multiscale Observational Science, ATMOS），该场地位于伊利诺伊州莱蒙特市阿贡国家实验室内，是一片占地20英亩的草原观测点。这些设备采用三位数字标识符（CMS-AMB-xxx）格式进行命名标识。数据以每日NetCDF（.nc）文件形式存储，每份文件包含约24小时的观测数据。文件命名遵循以下格式：项目名（CROCUS）、观测地点（atmos）、设备名称（CMS-AMB-001）、数据级别（raw、a1）以及观测日期（年、月、日）。可通过常用科学软件读取NetCDF格式数据，例如基于Python的xarray、netCDF4或ACT-DOE工具包。
