Abstract

The embodiment of the invention discloses a method and device for reconstructing a three-dimensional cloud body through satellite-ground cloud fusion, electronic equipment and a medium. The method for reconstructing the three-dimensional cloud body through satellite-ground cloud fusion comprises the steps of obtaining foundation cloud observation data of at least three cloud radars; acquiring multichannel scanning imaging radiometer data and cloud detection product data of the geostationary orbit meteorological satellite; performing space-time matching on the foundation cloud observation data, the multi-channel scanning imaging radiometer data and the cloud detection product data to obtain satellite-ground matching data; cloud top height inversion of a satellite in a preset area around each cloud radar installation point is realized based on the satellite-ground matching data, and the cloud top height of a cloud radar networking area is obtained; obtaining the cloud bottom height of the cloud radar networking area based on the ground-based cloud observation data; obtaining a three-dimensional cloud body boundary based on the cloud top height and the cloud bottom height; and obtaining a reconstructed three-dimensional cloud body based on the reflectivity factor profile and the radial speed profile in the foundation cloud observation data.

Description

technical field [0001] The present disclosure relates to the fields of atmospheric detection and atmospheric remote sensing, and in particular to a method, device, electronic device and medium for reconstructing a three-dimensional cloud body by fusion of stars, ground and clouds. Background technique [0002] One way to obtain cloud observation data is through the large-scale remote sensing observation of meteorological satellites, especially the relative position between the geostationary meteorological satellite and the earth remains unchanged, which can realize high-frequency continuous observation of the same location on the earth. Meteorological satellites can obtain large-scale cloud distribution, cloud amount, cloud shape and other information, and can also use the characteristics of cloud infrared radiation and temperature to further invert cloud top height information based on satellite infrared cloud images. However, since the satellite observation data is affecte...
