Office for Global Environmental Data Integration and Analytics

We provide support throughout the data life cycle from research planning to data acquisition, analysis, release, and data utilization. We operate the Global Environmental Database, GED, that collects, maintains, and widely disseminates data, and are also developing the Research Data Management System, RDMS, that enables research teams to manage data efficiently.
