Abstract

Statistical characteristics of data from coordinated lidar and radiometric sounding of the atmosphere carried out by ground-based solar radiometers and satellite lidar CALIOP were used as an input dataset for retrieving the altitude profiles of aerosol parameters. The signal-to-noise ratio of input satellite lidar signals increased when averaged over a general ensemble of experimental data. An algorithm and software package were developed for collecting and statistical processing of combined lidar and radiometric sounding datasets and calculating average aerosol optical parameters of an atmosphere model. Altitude profiles of average concentrations of aerosol fractions in the region of Belarus were calculated based on results of radiometric measurements at the Minsk site of the AERONET/PHOTONS network and lidar sounding data from CALIOP collected during the observation period from 2015 to 2019. A statistical approach to the synergy of satellite lidar and ground-based radiometric sensing data was effective for studying the long-term and large-scale aerosol changes in regions with low and medium contents of aerosol matter in the atmosphere.

研究气溶胶参数高度剖面的卡利奥普站和地面辐射测量站数据协同作用的统计方法
利用地面太阳辐射计和卫星激光雷达 CALIOP 对大气层进行的协调激光雷达和辐射探测数据的统计特征,作为检索气溶胶参数高度剖面的输入数据集。输入卫星激光雷达信号的信噪比在实验数据的总体平均值上有所增加。开发了一种算法和软件包,用于收集和统计处理激光雷达和辐射探测组合数据集,并计算大气模型的平均气溶胶光学参数。根据 AERONET/PHOTONS 网络明斯克站点的辐射测量结果和 CALIOP 在 2015 至 2019 年观测期间收集的激光雷达探测数据,计算了白俄罗斯地区气溶胶组分平均浓度的高度剖面图。卫星激光雷达和地面辐射测量传感数据协同作用的统计方法对于研究大气中气溶胶物质含量较低和中等的地区的长期和大规模气溶胶变化非常有效。
