摘要：

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.
