NOx和SO2的日平均值采用逐小时数据计算，且仅采用至少18小时数据计算的日平均值作为有效日平均值。NOx和SO2的月平均值是根据有效的日平均值数据计算的，如果数据是基于至少21个有效的日平均值(或2月份至少17个有效的日平均值)，则认为是有效的。年平均值是根据每年完整的月平均值数据计算的。如果一个月的平均数据不可用，我们使用在观察期间不同年份对应的月平均值的插值值。在中国，春天是从3月到5月，夏天是从6月到8月，秋天是从9月到11月，冬天是从12月到2月。

In this study, we introduced Lin'an Station (LAN; latitude 30 ° 18 ′ N, longitude 119 ° 44 ′ E), one of China's Global Atmospheric Observatory (GAW) stations; Measurement results of nitrogen oxides and sulfur dioxide at an altitude of 138.6 meters. We described the seasonal and diurnal variations of nitrogen oxide and sulfur dioxide mixture ratios observed in a local area network from 2006 to 2016, and studied their long-term trends. We also explained the observed changes and trends from the perspective of changes in meteorological conditions and emissions of these gases. This dataset shows the seasonal and daily variation characteristics of the mixing ratio of NOxand SO2observed at Lin'an Station from 2006 to 2016.
