Abstract

Measurements of fourteen selected H₂O absorption line parameters in the 720-nm region are presented. These results are compared to the most recent and relevant measurements. This paper presents a compilation of absorption cross sections of H₂O lines suitable for atmospheric humidity monitoring using an alexandrite laser source as the transmitter.
