Project Highlights and Future Plans

• ESMF-Compliant Coupling of WRF-LIS
• LISv4.0 has been coupled to WRFv.2.0.3.1 using
  ESMF v.2.1.0rp2 and a subcomponent coupling
  design
• Coupling needs to be generalized to handle
  multiple nests, projections and grids multiple
  PBLs and LSMs other than Noah and CLM2.
• Recognition
• LIS selected as co-winner of NASA 2005 Software
  of the Year Award
• Benchmarking on Columbia
• We have been allocated 150,000 hours on NASAs
  SGI Altix Supercomputer Columbia for benchmarking
  and additional scaling studies for the LIS/WRF
  and LIS/GCE coupled systems.
