Title: Ground transmission and emission intensity of the O2 1.27.MU.m nightglow.
Abstract: The transmission of the O2 1.27μm airglow to the ground is determined by coordinated measurements of a filter radiometer on board the S-310-16 rocket and a ground-based grating monochrometer. The inferred transmission of 6.3±3.4% for a zenith direction is in good agreement with the calculated value of 6.5% by EVANS et al. (1970). The zenith intensity of the 1.27μm nightglow is deduced to be 58±14kR, which is consistent with the rocket experimental result obtained by EVANS et al. (1972).
