TODO - In this paper we studied the temporal evolution of the Planetary
Boundary Layer height (PBLH) over the basin of Athens, Greece during a
5-year period (2011-2016) using data from the EOLE Raman lidar system.
The lidar data (range-corrected lidar signals-RCS) were selected around
12:00 UTC and 00:00 UTC for a total of 332 cases: 165 days and 167
nights. Extended Kalman filtering techniques were used for the
determination of the PBLH. Moreover, several well established techniques
for the PBLH estimation based on lidar data were also tested for a total
of 35 cases. Comparisons with the PBLH values derived from radiosonde
data were also performed. The mean PBLH over Athens was found to be of
the order of 1617 +/- 324 m at 12:00 UTC and of 892 +/- 130 m at 00:00
UTC, for the period examined. The mean PBLH growth rate was found to be
about 170 +/- 64 m h(-1) and 90 +/- 17 m h(-1), during daytime and
nighttime, respectively.
