北京大气试验站典型环境因素监测分析

摘要

对北京大气试验站典型环境因素(如温湿度、太阳辐射等气象因素及SO2、NO2、海盐离子等大气污染物)进行了长期监测.监测结果表明,该站年平均温度在12 ℃~14 ℃之间,年平均相对湿度为47 %,年太阳总辐射量低于5 600 MJ/m2;连续法测得SO2和NO2与其他污染物相比浓度偏高,但污染物总体浓度较低;该站具有内陆性气候、半乡村大气的特点.%The typical environmental factors of Beijing Atmospheric Test Station were monitored and analyzed, including air temperature, relative humidity, solar radiation and the air pollutants such as SO2, NO2 and chloride. The results showed that the average temperture was between 12 ℃~14 ℃; the average relative humidity was approximately 47 %; the total radiant energy was below 5 600 MJ/m2; the accumulative concentrations of pollutants were low in general, whereas SO2 and NO2 concentrations were higher than others; this station is a continental and semi-country climate.
