This book focuses on atmospheric remote sensing with spaceborne lidar, centering on the Daqi-1(DQ-1) Atmospheric Carbon Dioxide Lidar (ACDL) and its integrated HSRL and IPDA techniques for observing clouds, aerosols, and CO₂. It presents the theoretical foundations, hardware design, end-to-end simulation, retrieval algorithms, validation strategies, and representative applications of the system. Rich figures, tables, case studies, and a clear step-by-step structure make complex methods accessible. Readers will gain a systematic understanding of advanced active remote sensing technologies and their scientific applications. The book is especially valuable for researchers, graduate students, and engineers in remote sensing, atmospheric science, optical engineering, and earth observation areas.

Prof. LIU Dong is a full professor at the College of Optical Science and Engineering, Zhejiang University, and serves as the Deputy Director of the State Key Laboratory of Extreme Optics and Instrumentation. His research focuses on optical instrumentation and remote sensing, such as interferometry for extreme applications, machine vision for defect detection, and environmental lidar with long-term work spanning the development and application of the hardware and algorithm in space, atmosphere, marine, and environment areas. Built on sustained research in active remote sensing and optical instrumentation, this book reflects his expertise in spaceborne lidar theory, system design, retrieval methods, validation, and scientific applications, and will be of particular value to researchers, graduate students, and engineers in atmospheric remote sensing, optical engineering, and satellite observation etc.
