GSI-GFS Hybrid (sigma-pressure) Parallel

Experiment:

Operational GFS (T382 L64 out to 180 h, T190 L64 out to 384 h), using a sigma-pressure hybrid vertical coordinate.
New analysis scheme (GSI), performed on a 768 x 386 x 64 grid (post-processed to create spectral coefficients for model)
Current real-time experiment: PRZ

Verification:
          Forecast Verification (prz , pry  & ops)
          More forecast verification (including precipitation)

          Fits to observations (prz & pry)
          Fits to observations (prz & operations)

          Error diagnostics (powerpoint)
