The infrared absorption-spectra hygrometer possesses inherent advantages which will be of interest to the meteorologist concerned with difficult humidity-measurement problems. Data samples are presented which illustrate typical atmospheric humidity variations as obtained with a relatively uncomplicated experimental instrument featuring a short, 12-in sensing path. Also included is a discussion outlining method advantages in particular areas: micrometeorology, air weather reconnaissance, arctic meteorology, and other research applications.
