Firstly, conduct observer level quality control on the minute level nitric oxide concentration data collected at Shangdianzi Station in 2018; Secondly, with the support of data quality control software, hourly data is generated through expert level quality control; Then, hourly data is combined into a daily dataset. The daily dataset includes information such as CollectTime, DeviceName, DataValue, DataValueMax, DataValueTMx, DataValueMin, and DataValueTMn, which can be used for daily variation analysis of major atmospheric pollution gas nitric oxide data

The TE42i-TL nitrogen oxide analyzer produced by Thermo Fisher is used to collect minute level concentration data of nitrogen dioxide. The data unit is ppb and the data format is Excel (*. xls)
The original data is first subjected to singular value filtering, zero span checking, and other processes to eliminate problematic observation data. Then calibrate the data according to the calibration curve, and finally calculate the hourly and daily mean based on the effective data volume
The data has undergone two levels of quality control: observer level and expert level, and the data quality is good
