## Overview

This is a small soil-moisture fusion script: it loads SMAP, Sentinel, and NDVI arrays, builds pixel-level features and a weighted target, trains and applies a gradient-boosting regressor, then visualizes and saves the fused array. The README provides no further capability details; the workflow is based on the single sampled source file.

Main entry points: [`fusion.py`](https://github.com/varunnaikr/satellite-soil-moisture-fusion-ml/blob/main/fusion.py) (Fusion workflow), [`smap.npy`](https://github.com/varunnaikr/satellite-soil-moisture-fusion-ml/blob/main/smap.npy) (SMAP input), [`sentinel.npy`](https://github.com/varunnaikr/satellite-soil-moisture-fusion-ml/blob/main/sentinel.npy) (Sentinel input), [`ndvi.npy`](https://github.com/varunnaikr/satellite-soil-moisture-fusion-ml/blob/main/ndvi.npy) (NDVI input)
