From Szunyogh, Kostelich et al
• T62, 28 levels (1.5 million d.o.f.)
• The method is model independent: essentially the
same code was used for the L40 model as for the
NCEP global spectral model
• Simulation with observations at every grid point
(1.5 million obs)
• Very parallel! Each grid point analysis done
independently
• Very fast! 20 minutes in a single 1GHz Intel
processor with 10 ensemble members
