NASA Land Information System (LIS)
Entry ID: NASA_LIS
Abstract: The Land Information System (LIS) is a flexible land surface modeling and data assimilation framework developed with the goal of integrating satellite- and ground-based observational data products and advanced land surface modeling techniques to produce optimal fields of land surface states and fluxes. The LIS infrastructure provides the modeling tools to integrate these observations with the ... model forecasts to generate improved estimates of land surface conditions such as soil moisture, evaporation, snow pack, and runoff, at 1km and finer spatial resolutions and at one-hour and finer temporal resolutions.
The fine scale spatial modeling capability of LIS allows it take advantage of Earth Observing System (EOS)-era observations, such as Moderate Resolution Imaging Spectroradiometer (MODIS) leaf area index, snow cover, and surface temperature, at their full native resolution. LIS features a high performance and flexible design, provides infrastructure for data integration and assimilation, and operates on an ensemble of land surface models for extension over user-specified regional or global domains. LIS is designed using advanced software engineering principles to enable the reuse and community sharing of modeling tools, data resources, and assimilation algorithms.

LIS Sample Data Distribution Policy
LIS provides a collection of sample data for demonstration of LIS code. The
original source of each dataset is given whenever possible. LIS does not
endorse the validity, completeness, or usefulness of the datasets. Users are
strongly recommended to compile and validate their own datasets based on their
scientific goals. LIS has the built-in flexibility for users to easily
incorporate their own datasets. Please consult LIS User's Guide and Developer's
Guide distributed with LIS source code for details.
