NOAH shows you changes in rainfall and surface water patterns over the last four decades from across the planet.

There are red and green spots along the map, where bodies of water lie. The reds show areas where surface water has decreased while the greens indicate an increase. Black clusters represent water bodies that have remained the same.

To get started, you can enter a particular place into the search bar, or browse the map until you find some green or red clusters, and then directly click on a location to zoom in. A pop-up graph will appear with the area’s rainfall changes over time.

NOAH is built for anyone interested in learning about their environment. To see how your community is doing, click its location on the map, or jump into the search bar function. Start exploring.
