Problems solved by technology

Although ground-based cloud radar can provide time-continuous vertical cloud structure observations over the observation site, it has not yet formed an observation network, and it is difficult to obtain the distribution and evolution of the three-dimensional time-varying cloud field and cloud water field.
[0004] Clouds are discontinuous in time and space, and the existing technology lacks systematic observation methods, so it is difficult to obtain the distribution of three-dimensional cloud field and cloud water field, and it is also impossible to obtain accurate cloud water paths

Abstract

The invention provides a method and a device for obtaining a cloud water path. The method comprises the following steps: selecting at least one target region; obtaining space-time continued three-dimensional cloud water fields corresponding to each target region, wherein the three-dimensional cloud water fields are used for describing cloud water content corresponding to cloud in the vertical space corresponding to the target regions; obtaining at least one target atmospheric column in each three-dimensional cloud water field; and carrying out vertical integration on the cloud water content ofcloud in each target atmospheric column so as to obtain the cloud water path of the target atmospheric column. In order to obtain the cloud water path, an obtaining strategy for the related three-dimensional cloud water fields is also disclosed, according to the method for obtaining the cloud water path provided by the invention, the space-time continued cloud water content three-dimensional distribution result can be obtained on the basis of obtaining the three-dimensional cloud water fields, which is unavailable for conventional and special observation.

Description

technical field [0001] The invention relates to the field of data analysis, in particular to a method and device for acquiring a cloud-water path. Background technique [0002] The cloud field in the atmosphere is closely related to cloud radiation characteristics, precipitation mechanism and precipitation efficiency, and has great research value. Satellite observation, aircraft observation and ground cloud radar are the main means of cloud related research in the existing technology. [0003] However, it is currently impossible to obtain the spatial-temporal continuous three-dimensional cloud field observation results of an area based on satellite observations. As the most direct detection of cloud penetration, aircraft observation can only give the characteristics of clouds along the flight path. Although ground-based cloud radar can provide time-continuous vertical cloud structure observations over the observation site, it has not yet formed an observation network, and ...
