Action requires awareness.

Long-term environmental observations — from streamgages to ocean floats to weather radar — generate the data that science, policy, agriculture, public health, and conservation all depend on. Yet each year, without sufficient appreciation or funding, critical programs are reduced or lost entirely.

The Keeling Curve Foundation has compiled this database to make these programs visible to everyone who needs them: researchers, educators, decision-makers, donors, and citizens. Explore, filter, and discover the observations that are quietly watching over our planet.
