英文摘要 | The O-2(a(1)Delta g) emission near 1.27 mu m 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 OH dayglow produced by the hydrogen-ozone reaction (H+O-3 -> OH center dot+O-2) overlap the infrared atmospheric band emission (a(1)Delta(g) -> X-3 Sigma(g)) of O-2. 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 mu m O-2 dayglow limb-viewing observations. The O-2 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 O-2 dayglow and OH dayglow. It is apparent from the simulations that the presence of OH dayglow as an interfering species decreases the wind and temperature accuracy at all altitudes, but this effect can be reduced considerably by improving OH dayglow knowledge. |
