Abstract

The embodiment of the invention relates to the technical field of remote sensing technologies, and discloses a downscaling sea surface net radiation determination method, system and device and a storage medium. The method comprises the steps of firstly obtaining a preset downscaling estimation model; determining the net radiation of the first remote sensing data corresponding to the first spatialresolution through a preset downscaling estimation model to obtain the sea surface net radiation data corresponding to the second spatial resolution, wherein the value of the second spatial resolutionis smaller than the value of the first spatial resolution. According to the embodiment of the invention, because a downscaling processing mode corresponding to the preset downscaling estimation modelis used, the sea surface net radiation data with the smaller spatial resolution can be determined through the remote sensing data with the thicker spatial resolution, thereby solving the technical problem of being difficult to adapt to the smaller spatial resolution.

Description

technical field [0001] The invention relates to the technical field of remote sensing technology, in particular to a downscaled sea surface net radiation determination method, system, equipment and storage medium. Background technique [0002] The full-band net radiation of the sea surface is a state parameter used to characterize the energy budget of the sea surface radiation. This state parameter is helpful for studying the interaction process of sea surface-atmosphere boundary layer heat and water vapor and the cycle of ocean heat flux. The process, meanwhile, can also be used to predict some marine climate-related events. [0003] As far as the acquisition method of sea surface net radiation is concerned, the traditional acquisition method will use the data observed by buoys or volunteer ships, use the data to construct an empirical formula, and then use the empirical formula to estimate the sea surface net radiation. [0004] With the continuous development of technolo...
