TY - Data T1 - Daily data set of nitrogen dioxide at Shangdianzi atmospheric background station, Beijing, 2018 A1 - Ma Zhiqiang A1 - Shi Qingfeng DO - 10.12072/ncdc.SDZRAW.db0006.2021 PY - 2021 DA - 2021-07-26 PB - National Cryosphere Desert Data Center AB - For the minute level nitrogen dioxide concentration data collected at Shangdianzi station in 2018, the first step is to conduct observer level quality control; secondly, with the support of data quality control software, the hour data is generated through expert level quality control; and then the day data set is synthesized from the hour data. The daily data set includes information such as collection time, device name, data value, maximum value, maximum value (datavaluetmx), minimum value (datavaluemin), minimum value occurrence time (datavaluetmn), etc., which can be used for daily change analysis of nitrogen dioxide data of main air pollution gases.
