摘要:

皮埃尔·俄歇天文台的空气荧光探测器(FD)对于确定空气簇射能量尺度至关重要。为了补偿影响能量测量的大气条件变化,天文台操作一系列监测仪器,每小时记录探测器现场的大气条件,面积超过3,000平方公里。本文介绍了用于表征大气气溶胶成分的四种仪器的结果:中央激光设施(CLF),它为FD提供校准的激光照射;扫描后向散射激光雷达,它在三个FD站点工作;气溶胶相函数监测器(APF),它在两个FD位置测量气溶胶散射截面;水平衰减监测器(HAM),测量气溶胶衰减的波长依赖性。

英文摘要:

The air fluorescence detectors (FDs) of the Pierre Auger Observatory are vital for the determination of the air shower energy scale. To compensate for variations in atmospheric conditions that affect the energy measurement, the Observatory operates an array of monitoring instruments to record hourly atmospheric conditions across the detector site, an area exceeding 3,000 square km. This paper presents results from four instruments used to characterize the aerosol component of the atmosphere: the Central Laser Facility (CLF), which provides the FDs with calibrated laser shots; the scanning backscatter lidars, which operate at three FD sites; the Aerosol Phase Function monitors (APFs), which measure the aerosol scattering cross section at two FD locations; and the Horizontal Attenuation Monitor (HAM), which measures the wavelength dependence of aerosol attenuation.
