CROCUS Weather Data at Northeastern Illinois University Rooftop

This dataset is from the Department of Energy Office of Science funded project, Community Research on Urban and Climate Science (CROCUS) (https://crocus-urban.org/). Vaisala WXT sensor is an all-in-one weather instrument that provides 6 of the most important weather parameters: barometric pressure, temperature, relative humidity, rainfall, wind speed and direction. Temperature, pressure, relative humidity, and rainfall are sampled at 1 second frequency, while wind speed/direction is measured at ten per second (10Hz) frequency. These measurements are useful for looking at characterizing local weather, identifying unique weather events, and studying local turbulence, especially given the high temporal resolution of the wind measurements. Datasets are stored in the netCDF data format, and we we encourage users to make use the associated toolkits available from Unidata (https://www.unidata.ucar.edu/software/netcdf/), Project Pythia (https://foundations.projectpythia.org/core/data-formats/netcdf-cf.html), and our “Instrument Cookbooks” (https://crocus-urban.github.io/instrument-cookbooks) for more information on how to process the metadata-rich datasets.

本数据集源自美国能源部科学办公室资助的城市与气候科学社区研究（Community Research on Urban and Climate Science, CROCUS）项目（https://crocus-urban.org/）。Vaisala WXT型一体式气象综合观测仪可提供六大核心气象参数：大气压强、气温、相对湿度、降雨量、风速与风向。其中，气温、压强、相对湿度与降雨量的采样频率为1秒，风速与风向的测量频率则为10赫兹（10Hz）。此类测量数据可用于表征局地气象特征、识别特殊气象事件以及研究局地湍流，尤其得益于其风速测量具备的高时间分辨率。数据集采用netCDF（网络通用数据格式）存储，我们鼓励用户借助Unidata（https://www.unidata.ucar.edu/software/netcdf/）、Project Pythia（https://foundations.projectpythia.org/core/data-formats/netcdf-cf.html）以及本项目的Instrument Cookbooks（仪器指南手册，https://crocus-urban.github.io/instrument-cookbooks）提供的配套工具包，以掌握此类富含元数据的数据集的处理方法。
