NU-WRF Source Code and Data

The release of NU-WRF software is subject to NASA legal review, and requires users to sign a Software Usage AgreementToshi Matsui (toshihisa.matsui-1@nasa.gov) and Carlos Cruz (carlos.a.cruz@nasa.gov) are the points of contact for discussing and processing requests for the NU-WRF software.

  • Source Code Repository - Development source code is stored on an NCCS  (NASA Center for Climate Simulation) sponsored Gitlab server which is accessible by invitation. Older NU-WRF releases are available in a tarball and can be obtained after signing the software release agreement. The source code includes various NU-WRF components, WRF packages, utilities, and test cases for the project. 
  • Shared folder - large data folder located on NCCS discover system holds libraries, use case data sets, and official NU-WRF releases managed by ASTG. 

More information on how to get the source code is available in the Modeling Guru NU-WRF Source Code and Data site. 

Running NU-WRF 

 The NU-WRF source code requires Fortran 90/2003, C, and C++ compilers. The current release officially supports Intel compilers 18.0.3.222 (ifort, icc, and icpc) on DISCOVER (at NASA Goddard Space Flight Center) and PLEIADES (at NASA Ames Research Center). A large number of third party libraries must be installed before building NU-WRF. Details are available in the NU-WRF userguide. Each component of the NU-WRF modeling system has a unique compilation mechanism, ranging from simple “Makefiles” to sophisticated Perl and shell scripts. To make it easier for the user to create desired executables and to more easily resolve dependencies between components, NU-WRF includes a high level “wrapper” Python script for compilation. The latest NU-WRF release currently uses Intel-MPI on DISCOVER and PLEIADES; SGIMPT is also available on DISCOVER and Pleiades. Sample workflows are presented in NU-WRF userguide to initialize and run WRF in multiple confgurations as well as post processing the WRF / LIS model output.
