New TMerge framework improves satellite precipitation estimates using tensor factorization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel tensor-based framework called TMerge to improve the accuracy of satellite precipitation estimates. By representing daily precipitation data as spatiotemporal tensors and applying CANDECOMP/PARAFAC factorization, the method captures the inherent low-rank structure of precipitation. When applied to correct IMERG Final Run data using reference observations over the contiguous United States, TMerge significantly enhanced correlation and reduced error metrics compared to existing methods, including neural networks. AI

IMPACT This tensor-based approach could enhance climate modeling and weather forecasting by providing more accurate precipitation data.

    Low-rank tensor structure of precipitation and its application to satellite-reference merging

    arXiv:2610.11000v1 Announce Type: new Abstract: The intermittent and variable nature of precipitation makes its accurate estimation over extended domains difficult, yet its spatiotemporal structure suggests that a low-rank representation may be possible. This work represents dail…
