Abstract: The Land Information System (LIS) provides collection of sample data for demonstration of LIS code. The original source of each data set is given whenever possible. LIS does not endorse the validity, completeness, or usefulness of the data sets. Users are strongly recommended to compile and validate their own data sets based on their scientific goals. LIS has the built-in flexibility for users to ... easily incorporate their own data sets.
The sample data are archived and served in three categories:
1. land surface parameters 2. atmospheric forcing 3. LIS model output.
They are available either by: HTTP, which enables you to directly download data files; or by GrADS-DODS server (GDS), which enables you to access a user-defined subset of the sample data.
A web-based visualization system called "Land Explorer" (LE) has been developed to visualize the data sets. LE tightly integrates with the LIS Grads-DODS server. It is designed to let users interactively visualize and explore the sample and other data sets at all resolutions, featuring an intuitive web interface and fast response.
Users must register to download data.

The LIS data and related software is provided "as is" without any warranty of any kind, either expressed or implied, or statutory, including, but not limited to, any warranty that the LIS data and related software will conform to specifications, any implied warranties of merchantability, fitness for a particular purpose, and freedom from infringement, and any warranty that the documentation will conform to the LIS data and related software, or any warranty that the LIS data and related software will be error free. This agreement does not, in any manner, constitute an endorsement by NASA of any test results, resulting designs, hardware, or other matters resulting from use of the LIS data and related software. The User shall not file any claim against the United States or developers of the LIS data and related software for any matter concerning the LIS data and related software, performance of, failure to perform, breach or other matter related to this agreement. The User's sole remedy for any such matter shall be the immediate, unilateral termination of this agreement. The United States and the developers of the LIS data and related software shall not be liable for any damage or injury suffered by the User or its representatives, regardless of cause, and the User hereby expressly waives any rights it might otherwise have under the Federal Tort Claims Act or any other authority, in consideration for NASA's agreement to provide the LIS data and related software under this agreement. User, under this section, includes any further user to which the User provides the LIS data and related software and/or works based upon the LIS data and related software.
The User shall indemnify and hold harmless the United States and the developers of the LIS data and related software from any third party liability arising under the Federal Tort Claims Act or any other authority, out of the LIS data and related software, or out of performance of, or failure to perform, any aspect of this agreement, whether or not caused by the negligence, gross negligence or willful misconduct of employees of the United States or the developers of the LIS data and related software. User, under this section, includes any further user to which the User provides the LIS data and related software and/or works based upon the LIS data and related software.
This agreement shall be subject to United States federal law only, for all purposes, including, but not limited to, determining the validity of this agreement, the meaning of its provisions, and the rights, obligations and remedies of the parties.
This agreement constitutes the entire understanding and agreement between the parties hereto relating to the use of the LIS data and related software and may not be superseded, modified or amended, except by further written agreement duly executed by the parties.
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.
