Planetary boundary layer height (PBLH) over the SGP

Given the rapid change in clouds over land, radiosonde observations have limitations when it comes to tracking cloud development due to the coarse temporal resolution and drifting of the balloon. We thus developed a lidar-based method to identify the coupled states of clouds based on our new algorithm for retrieving the PBLH that can better track the diurnal variations in PBLH than conventional lidar-based approaches (Su et al., 2020). We adapted this algorithm for retrieving the PBLH and developed a new scheme to deal with cloudy conditions (Su et al., 2022). Following the original method (Su et al., 2020), the rainy cases are eliminated in the quality-control process. The quality-control flag is provided in the dataset file.
