We investigate the temporal evolution of the planetary boundary-layer (PBL) height over the basin of Athens, Greece, during a 6-year period (2011–2016), using data from a Raman lidar system. The range-corrected lidar signals are selected around local noon (1200 UTC) and midnight (0000 UTC), for a total of 332 cases: 165 days and 167 nights. In this dataset, the extended-Kalman filtering technique is applied and tested for the determination of the PBL height. Several well-established techniques for the PBL height estimation based on lidar data are also tested for a total of 35 cases. The lidar-derived PBL heights are compared to those derived from radiosonde data. The mean PBL height over Athens is found to be 1617 ± 324 m at 1200 UTC and 892 ± 130 m at 0000 UTC for the period examined, while the mean PBL-height growth rate is found to be 170 ± 64 m h −1 and 90 ± 17 m h −1 during daytime and night-time, respectively.

扩展卡尔曼滤波技术在确定希腊雅典上空行星边界层高度中的应用与测试

我们使用拉曼激光雷达系统的数据调查了希腊雅典盆地在 6 年期间（2011-2016 年）的行星边界层 (PBL) 高度的时间演变。距离校正激光雷达信号选择在当地中午（1200 UTC）和午夜（0000 UTC）前后，共 332 个案例：165 天 167 夜。在这个数据集中，扩展卡尔曼滤波技术被应用和测试以确定 PBL 高度。还对基于激光雷达数据的 PBL 高度估计的几种成熟技术进行了总共 35 个案例的测试。将激光雷达导出的 PBL 高度与无线电探空仪数据导出的高度进行比较。发现雅典上空的平均 PBL 高度在 1200 UTC 时为 1617 ± 324 m，在 UTC 时为 892 ± 130 m，在检查期间，
