| 摘 要： | 利用中分辨率红外光谱仪于1999年秋采暖前后在北京进行了为期两个月的CO、水汽等大气微量成分柱总量的测量.测量结果表明,采暖后北京市区CO柱总量较采暖前有所增加,采暖前CO柱总量较小,日均值为0.147 atm-cm,而采暖后CO柱总量较大,前7天的日均值为0.205 atm-cm,相应地日变化也比较大.但是,大气中的CO柱总量受到气象条件的重要影响,影响CO柱总量逐日变化和日变化的气象因子主要有大气稳定度、风速和风向等.

| Abstract: | CO, water vapor and other trace gases have been measured in Beijing during the transition period of heating in the fall of 1999, using an infrared grating spectrometer of moderate resolution. The measurements show that the CO column amount over Beijing urban area after heating is larger than that before heating. The CO column amount before heating is smaller, the daily average is 0.147 atm-cm, while that after heating is larger, the daily average of the first 7 days is 0.205 atm-cm, and the daily variation is larger as well. However, the variation of CO column amount is closely dependent on meteorological condition, mainly including atmospheric stability, wind speed and wind direction. |
