The Center for Integrated Earth System Information (CIESIN) is a center within the Columbia Climate School at Columbia University. CIESIN conducts cutting-edge geospatially enabled research and develops interdisciplinary data and systems to advance understanding of human-environment interactions and support public policy and private decision making.

Notice: The contract for the CIESIN-managed NASA Socioeconomic Data and Applications Center (SEDAC) was terminated on 30 April 2025. SEDAC data sets disappeared from NASA Earthdata for approximately two months, but are now back online via Earthdata Search.  At the same time, CIESIN plans to transition its data to the CAFE collection of the Harvard Dataverse. Data sets should start appearing there in July. For further information please contact [email protected].
