AI framework detects groundwater anomalies in Ghana using satellite data

Researchers have developed an unsupervised machine learning framework to detect groundwater storage anomalies in Ghana using data from the GRACE satellite. The study analyzed groundwater variability from 2004 to 2024, identifying 12 anomalous months, including significant deficits and surpluses. The findings indicate persistent groundwater deficits in the early period, followed by increasing positive anomalies, with spatial variations showing more frequent deficits in northern Ghana and surpluses in the south. This approach offers a practical method for groundwater monitoring in regions with limited in-situ data. AI

IMPACT This research demonstrates a novel application of unsupervised machine learning for environmental monitoring in data-scarce regions.
