AI Technical Summary

Technical Problem

Existing satellite-based precipitation correction technology lacks a lightweight network architecture, resulting in high resource consumption, slow processing speed, and inability to adapt to near real-time processing scenarios. Furthermore, the spectral fidelity assessment of the inverted data is not comprehensive enough, making it difficult to form an accurate quality mask matrix, which affects the reliability of data applications.

Method used

A lightweight correction network based on machine learning is used to reshape the tensor and reconstruct the channel dimension of the inverted precipitation data in the satellite inversion section, generate network-adaptive feature primitives, and generate a quality mask matrix through spectral fidelity evaluation. Combined with spatiotemporal kriging interpolation and edge smoothing fusion, a seamless correction field is generated.

Benefits of technology

It significantly improves the correction accuracy and application value of satellite-retrieved precipitation data, meets near real-time processing requirements, and ensures data integrity, consistency, adaptability, and efficiency.
