A Comparative Study of Long‐Term Variability of Urban and Suburban Planetary Boundary Layer Heights Using Ceilometers and the HRRR Model
An adaptive algorithm has been developed using ground‐based high‐resolution aerosol backscatter profiles from the Vaisala CL61 ceilometer to retrieve planetary boundary layer height (PBLH). Datasets spanning more than 3 years (2022–2025) from the U.S. National Capital Region (NCR) were comprehensively analyzed. We fo...
