Ion content and infrared absorption of moist atmospheric air
Abstract
New measurements have been made of anomalous infrared absorption in moist air using a White cell and optical path lengths of 56.4 and 94.0 m. Simultaneous measurements were made of the ion content of the moist air, which was humidified by boiling water in a recirculating system. Data are presented for absorption cross section, self-broadening coefficient, and ion content as functions of humidity. The results show that the infrared absorption is proportional to the ion content of moist air, and that the observed behavior is consistent with the theory that ions are formed by dissociation of huge populations of large neutral clusters that are formed by evaporation, and these are responsible for much of the infrared continuum absorption. Other theoretical aspects and projected work are discussed briefly.
