Mesoscale Parallel Experiment Log

Experiment
North American WRF-NMM run with 1) cycled data assimilation using Grid-point Statistical Interpolation (GSI) analysis, and 2) version 1.3 of WRF-NMM using the "NMMx" version described here. Integration domain covers about 1/2 of the ops NAM 12 km domain.

Special treatment of land states for this parallel:

  • Land-states from ops NDAS replace cycled states from WRF-NMM at the start of each NDASx cycle, and at the start of each NAMX 84-h forecast
  • Use ops Eta terrain heights
