AI Technical Summary

Technical Problem

Existing three-dimensional atmospheric tomography methods mainly rely on fixed site locations and fixed tomographic boundaries, which makes it difficult to adapt to highly dynamic aircraft carriers. This results in low horizontal and vertical resolution, failing to meet the demand for high spatiotemporal resolution water vapor information acquisition.

Method used

A three-dimensional atmospheric tomography method based on low-altitude airborne BeiDou observations is proposed. By acquiring dynamic airborne BeiDou observation data, processing the data using pre-set GNSS processing software, and combining dynamic adaptive tomography boundary optimization algorithm and adaptive algebraic reconstruction algorithm, a BeiDou atmospheric tomography observation equation is constructed. Gaussian filtering is then used for smoothing to achieve high spatiotemporal resolution three-dimensional atmospheric tomography.

Benefits of technology

It enables high spatiotemporal resolution monitoring of water vapor distribution and vertical variation, captures local water vapor anomalies, improves numerical weather models, expands the operational value of water vapor meteorology, and enhances the ability to issue early warnings for extreme weather.
