Improving Daytime Planetary Boundary Layer Height Determination from CALIOP: Validation Based on Ground-Based Lidar Station

Figure 6

Vertical profiles of total attenuated backscatter at 532 nm under clear sky conditions, in which (a) is for CALIOP and (b) is for CE370. In (a), the PBLH results derived by wavelet method (red line), improved maximum variance method (purple line), and integrated algorithm (black bold line) are, respectively, shown in the same figure along with latitude and longitude; (b) is similar to Figure 3(b), but for another day. The PBLH results (black points) were derived from CE370 during daytime. The vertical white solid lines in (a) and (b) indicate the points of the nearest spatial and temporal coincidence between CALIOP footprints and CE370 Lidar site, and (c) shows the comparison of vertical profiles of backscatter signals and PBL top height results between CALIOP and ground-based Lidar. The vertical profiles are corresponding to the vertical white solid lines in (a) and (b).
