CROCUS Air Quality 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/). The AQT (Vaisala AQT530) instrument provides observations on meteorological conditions, including particulate matter (PM2.5, PM10), gas species concentrations (NO, NO2, O3, CO), and environment temperature and moisture. These measurements are critical for understanding air quality. These measurements are useful for understanding changes in aerosol properties, air quality research, and comparing to model experiments especially in urban environments. 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，项目官方网址为https://crocus-urban.org/。该数据集依托AQT（Vaisala AQT530）型观测仪器完成数据采集，可获取气象相关观测参数，包括颗粒物（PM2.5、PM10）浓度、气态污染物（NO、NO2、O3、CO）浓度以及环境温湿度数据。此类观测数据对于解析空气质量具有核心价值，可用于探究气溶胶特性演变、开展空气质量相关研究，尤其适用于城市环境下的相关分析，并可与模型实验结果进行比对验证。数据集采用netCDF格式存储，我们鼓励用户借助Unidata（https://www.unidata.ucar.edu/software/netcdf/）、Pythia项目（https://foundations.projectpythia.org/core/data-formats/netcdf-cf.html）以及本项目的"Instrument Cookbooks"（https://crocus-urban.github.io/instrument-cookbooks）提供的配套工具包，学习如何处理这类富含元数据的数据集。
