Water Vapor Absorption Parameters For Selected Lines, 715-732nm And 932-961nm(1)

Abstract

Absolute absorption measurements were made on 172 selected lines in the near IR spectrum of H2O. Line strengths and N2 pressure broadening coefficients were determined with standard deviations in the range 1-5% for a majority of the lines. Self-broadening coefficients and pressure shifts were also measured for several lines. The line selection criteria were based on the requirements for remotely measuring atmospheric humidity profiles with narrow-band, tunable, pulsed lasers by means of light detection and ranging (lidar).
