What is it about?
We used machine learning to make satellite rainfall data more detailed for a basin shared by Ecuador and Peru, an area with limited rain gauges. By combining satellite information with environmental and geographic data, we created higher-resolution rainfall maps that better reflect local conditions. Our approach helps provide more accurate rainfall information where it is most needed for water management.

Why is it important?
Accurate rainfall data are essential for managing water resources, especially in regions with few weather stations. Our work delivers the first high-resolution rainfall maps for this important Andean–Pacific basin, supporting better planning for agriculture, flood prevention, and climate adaptation in both Ecuador and Peru. The methods can be easily adapted for other regions facing similar data challenges.
Perspectives
I am proud that this work bridges advanced data science and real-world water management needs in a critical transboundary region. It shows how local expertise and smart technology can make a difference for communities facing water scarcity and climate uncertainty.
