LIS Documentation


LIS 5.0 Documentation

A more complete library of LIS documentation for different versions of LIS can be found in the LIS section of the NASA Modeling Guru website.


Source Code Documentation

NOTE: LIS 5.0 employs ESMF Configuration Object, which by default has a resource file size limitation of 200 lines. This limit could cause problems on some platforms. To bypass this, we recommend the following fix to the ESMF code. Download ESMF, go to
esmf/src/Infrastructure/Config/src/ESMF_Config.F90 file,
change the line:
integer, parameter :: MSZ = 200 to
integer, parameter :: MSZ = 500
before building the ESMF library.

LIS source code is maintained in a Subversion Repository. You must have the Subversion client software, svn, installed on your computer in order to get, or "checkout", a copy of the LIS source code.
See: Subversion Checkout Instructions.

Input Data

A number of sample input data are provided along with the LIS testcases on the LIS testcases page.

The high resolution parameter datasets, due to their large filesizes, are not provided for download. Please contact us if you would like to access sample LIS data at high resolutions such as 1km. Once the 1km sample datasets are downloaded, data at coarser resolutions can be generated using a number of helpful programs described in the LIS Data Processing Guide

Output Data

The LIS testcases page provides sample output corresponding to each testcase.
