The NASA Land Information System (LIS) Program provides advanced land surface modeling and data assimilation capabilities for use in research and operational applications. Through partnerships with government agencies, academic institutions, and industry, the LIS Program enables the integration of satellite and ground-based observations with models to improve our understanding of Earth’s land surface processes. The program’s open-source framework also allows for the development of new land surface models and the sharing of data and code across the scientific community.
