Abstract

The invention provides a sea surface net radiation estimation method and system. The sea surface net radiation estimation method comprises the steps of obtaining target multi-source data of a sea surface area to be measured, wherein the target multi-source data comprises remote sensing data, reanalysis data and site actual measurement data of the to-be-measured sea surface area; inputting the target multi-source data into a sea surface net radiation estimation model, and outputting first net radiation of the sea surface area to be measured, wherein the sea surface net radiation estimation model is obtained by taking sample multi-source data of a sample sea surface area as a sample and taking site actual measurement net radiation of the sample sea surface area corresponding to the sample as a sample label for training. According to the method and system, the sea surface net radiation estimation is carried out by integrating multiple data sources, respective advantages of different data sources are exerted, the resolution and precision of sea surface net radiation estimation are improved, and long-time-sequence, high-precision and high-resolution sea surface net radiation estimation can be achieved.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a sea surface net radiation estimation method and system. Background technique [0002] Ocean surface net radiation is an important parameter that characterizes the ocean surface energy budget. As an important part of the global energy balance, it together with the sea surface turbulent flux determines the energy available to the sea surface, which in turn affects the ocean and the atmosphere. climate. The heat exchange at the air-sea interface reflects the interconnection and feedback mechanism between the ocean and the atmosphere. The ocean radiative transfer process is one of the most important physical processes in the atmosphere-ocean system, which strongly affects the atmospheric circulation and ocean circulation, and is responsible for climate change at different scales. Therefore, the net radiation of the ocean surface plays an important role in the interaction be...
