The FIM Global Model
http://fim.noaa.gov/

A unique combination of 3 numerical design features Icosahedral horizontal grid, mostly hexagons except for 12 pentagons ("I" in FIM) Isentropic-sigma hybrid vertical coordinate, adaptive, concentrates around frontal zones, tropopause, similar to RUC model ("F" for Flow-following in FIM) Finite-volume horizontal transport (Also under "F", for "finite-volume" in FIM).

It is just as accurate as the EURO.
