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

Figure 3

Vertical profiles of total attenuated backscatter at 532 nm; (a) was acquired from CALIOP, while (b) was acquired from ground-based Lidar (CE370), which were all measured on December 31, 2015. The PBLH results derived by the maximum variance method developed by Jordan et al. (red bold line) and the improved maximum variance method (black line) are, respectively, shown in (a) along with latitude and longitude, while in (b), the PBLH results (black points) were derived by wavelet method from CE370 observations during daytime, which are relative to sea level. The vertical white solid lines in (a) and (b) indicate the points of the nearest spatial and temporal coincidence between the CE370 Lidar site and the CALIOP footprint.
