The invention relates to the technical field of atmospheric physics, and particularly discloses an inversion radiation method based on a satellite cloud atlas, which comprises the following steps: acquiring satellite cloud atlas data; performing image processing on the satellite cloud picture data to obtain a cloud index; establishing a clear sky model, and obtaining a radiation attenuation indexaccording to the clear sky model and the actually measured radiation value; establishing a corresponding mathematical relationship according to the cloud index and the radiation attenuation index; andcalculating according to the mathematical relationship to obtain regional radiation data. The inversion radiation method based on the satellite cloud atlas provided by the invention can replace radiation data of a ground-based radiation station, saves high cost for constructing the ground-based radiation station and labor cost for controlling data quality, and more visually reflects the change condition of a radiation field of the whole region.
Description
technical field [0001] The invention relates to the technical field of atmospheric physics, in particular to a radiation inversion method based on satellite cloud images. Background technique [0002] Surface radiation is one of the observation items of radiation stations in my country. The study of surface radiation is of great significance for understanding the occurrence, development, layout, and structure of ecosystems in different regions, and it is one of the factors in the study of the water and heat balance equation of ecosystems. Surface radiation is also an important indicator for evaluating the urban environment, especially for judging the strength of the urban heat island effect, which can help us understand and improve the urban environment and improve the quality of human life. Surface radiation reflects the distribution of heat resources on the ground, which is also necessary for us to make full use of energy and reduce disasters. [0003] However, the curre...
