【摘要】 水汽体积比仅仅占整个空气的0.1%~3%,但它却是大气中时空变化最活跃的气体。随着光电探测技术的不断发展,大气衰减对光电探测造成的影响也越来越显著,其中水汽是主要影响因子之一,也是最为不确定参数。拉曼激光雷达由于其测量精度高及自动化程度高,成为现今测量大气水汽含量的新型工具。文中介绍了自行研制的水汽测量拉曼激光雷达的总体结构和主要技术参量。测量结果显示,该激光雷达可以对夜晚6km高度范围内以及白天边界层内的水汽进行测量。实验数据与当地探空数据进行比对,取得了较好的一致性,充分验证了该拉曼激光雷达测量水汽的有效性和可靠性。更多还原

【Abstract】 The content of water vap or in atmosp here is very little and the volume ratio of moisture to air is about 0.1%~3%, but water vap or is the most active mo lecu le in atmosp here. The influen ces of atmosp heric attenuation become more serious alon g with the develop ment of the optics-electron detecting technolo gy. The water vap or in the atmosp here is the main f actor and uncertain p arameter to affect atmosp heric attenuation. Due to advantages of the h igh measurin g r ecision and automatic op eration, the Raman lidar has become the useful advantaged tools to measure water vap or. The system structure and sp ecifications of Raman lidar d evelop ed by our institute are introduced. The measurement results show that this lidar can take measurements of water vap or over 6 km h eight at night and water vap or in bound ary lay er in day time as well as the trop osp heric aerosol in day and night continuously. The obtained results are better consistent with radiosonde data in terms of the water vap or, which assures the reliability and availab ility of the Raman lidar for water vap or observation.更多还原
