Mesoscale Parallel Experiment Log

Experiment
North American WRF-NMM run with
  1. cycled data assimilation using Grid-point Statistical Interpolation (GSI) analysis
  2. version 2.1 of WRF-NMM (2/2006 repository version) go to the NAMX parallel change log for all changes in NAMY prior to 00Z 3/2/2006 for details.
  3. Fully cycled land-states using G. Gayno's surface update codes; SST, snow, sea ice updated at the start of each 00z assimiltion cycle
  4. NMM terrain and roughness length from G. Gayno utilities.
  5. Model top pressure moved from 50 mb to 2 mb, vertical layer distribution modified to maintain the same thickness of the lowest layer as is in NAM.
  6. GSI analysis uses NMM-based background errors
  7. Additional physics/analysis tests prior to handoff of code changes to NCO for real-time parallel NAMX on white
