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 (12/2005 repository version) go to the old NAM parallel change log 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 GFS-based background error covariances (changed to NMM-based background errors on 1/21/2006)
Integration domain previously covered about 1/2 of the ops NAM 12 km domain, changed to full ops NAM domain at 12z 12/27/2005 (see change log).
