NEW FEATURE	STRENGTH	RISK
32km Horizontal Resolution	representation of terrain	small
3DVAR data assimilation	can handle non-standard observations	it is a new system and could introduce new errors
domain size smaller than Eta-48 but much larger than Eta-29.	reduces errors from lateral boundaries	western boundary is closer to WR than in Eta-48
Vertical Resolution	better than in Eta-48	won't eliminate PBL problems
clouds and soil moisture cycled from Eta not AVN.	Reduces spin-up problems in QPF, etc.	Eta was developed using AVN first-guesses, so new errors are possible
3-hr Boundary Condition Updates	reduces errors from lateral boundaries	small
new surface pressure treatment	assimilate more surface observations	small
new driver to update mass and wind each time step	removes spurious high-frequency waves	small
