Two Satellites Fill the Soil-Moisture Gaps
A dual-branch Transformer combines GNSS reflections from Tianmu-1 and Fengyun-3 into broader coverage.
Summary
A dual-branch Transformer combines GNSS reflections from Tianmu-1 and Fengyun-3 into broader coverage.
The model learns each satellite separately before fusing them on a 36-kilometer grid. The product reached 79.7% average monthly coverage and a reported 0.88 correlation with NASA's SMAP reference. Ground comparisons were weaker and arid regions performed best, so broader validation remains necessary.
Why it matters
