Past Releases

We recommend using the most current version. Support is no longer provided for the following past versions.

WRF-Hydro® Coupling with Other Systems

Noah and NoahMP LSM/HRLDAS

WRF-Hydro® users who use the Noah land surface model will find information specific to the Noah and NoahMP LSM and the accompanying 'High Resolution Land Data Assimilation System (HRLDAS)' at http://www.ral.ucar.edu/research/land/technology/lsm.php

NASA Land Information System (LIS)

WRF-Hydro® users who are interested in using the NASA Land Information System (LIS) with WRF-Hydro® will find information specific to LIS at http://lis.gsfc.nasa.gov/.
Note: The coupling to LIS is presently at a prototype stage and no user support for this is presently available.

NCAR Community Earth System Model/Community Land Model (CESM/CLM)

WRF-Hydro® users who are interested in using the NCAR Community Earth System Model/Community Land Model (CESM/CLM) with WRF-Hydro® will find information specific to those models at http://www.cgd.ucar.edu/tss/clm/.
Note: The coupling to CESM/CLM is presently at a prototype stage and no user support for this is presently available.
