Abstract
Water vapor lidar has made it possible to continuously observe water vapor in the atmosphere and is a prominent tool for studying the hydrological cycle, cloud formation, and atmospheric convection. However, a standardized quality control method for managing the accuracy and number of available data has not been established, as well as a method for determining the appropriate spatial resolution. We propose a concise, visual framework in which observed data is plotted to determine the uncertainty threshold and spatial resolution of lidar data. Application of the method to observed data showed that it is effective for determining the optimum uncertainty threshold and the finest vertical resolution for balancing the accuracy and data quantity at every altitude range.
