Inter-airway temperature (T
a
), absolute humidity (AH) and ASL water equivalent height (H
e,ASL
) distribution from rest to maximal change during inhalation of ambient air at T = 23°C, RH = 45% (AH = 9.2g H2O/m3 dry air). Arrows indicate direction of change. Non-dimensional airway position (X/L), defines the ratio of distance from anterior nasal valve to the posterior choanae within the two airways.
