Effect of OH emission on the temperature and wind measurements derived from limb-viewing observations of the 1.27 μm O2 dayglow

Abstract

The O2(a1δg) emission near 1.27 μm is well-suited for remote sensing of global wind and temperature in near-space by limb-viewing observations to its bright signal and extended altitude coverage. However, vibrational-rotational emission lines of the O2. The main goal of this paper is to discuss the effect of OH emission on the wind and temperature measurements derived from the 1.27 O2 dayglow limb-viewing observations. The O2 dayglow and OH dayglow spectrum over the spectral region and altitude range of interest is calculated by using the line-by-line radiative transfer model and the most recent photochemical model. The method of four-point sampling of the interferogram and sample results of measurement simulations are provided for both
