Is the acceleration of a falling body greater than g in the presence of air resistance?
Air resistance decelerates objects. If the object were falling downwards, then air resistance would mean that the object would accelerate less that under the effect of gravity alone: Air resistance reduces acceleration. If the object were shooting upwards, then air resistance and gravity would be working together to decelerate the object. In this case, acceleration (downwards) would be greater than usual due to air resistance.
