因为先前对地基气辉测量的解释所使用的光化学速率系数与从“大气探险者”系列测量中推导出的系数有很大不同，所以就产生了一个问题：AE速率在解释地基数据方面是否像在解释卫星数据方面那样成功。在本文中，我们使用AE光化学来解释在阿雷西博天文台对O I（6300埃）和N I（5200埃）气辉表面亮度以及由非相干散射雷达测量的电子密度和温度剖面所做的同步观测。我们发现，对于5200埃的发射，理论和实验是一致的。然而，我们无法使6300埃夜气辉完全一致，并认为差异的根源在于用于计算O(¹D)产生率的参数之一。数据清楚地表明，在F层下降和上升期间，电离层存在不对称行为。这种不对称可能反映了输运对F区底部分子离子密度的影响。我们的结果支持N(²D)和O之间的猝灭反应速率较低。计算表明，气辉表面亮度的测量对大气中原子氮的丰度相对不敏感。
Because previous interpretations of ground-based airglow measurements have used photochemical rate coefficients quite different from those deduced from the Atmosphere Explorer series of measurements, the question arises of whether the AE rates are as successful at explaining ground-based data as they are at explaining satellite data. In this paper we use the AE photochemistry to interpret simultaneous observations made at the Arecibo Observatory of the O I (6300 A) and N I (5200 A) airglow surface brightness and electron density and temperature profiles measured by incoherent scatter radar. We find that theory and experiment are in agreement for the 5200-A emission. However, we are unable to obtain complete agreement for the 6300-A nightglow and suggest that the source of the discrepancy lies with one of the parameters used to calculate the production rate of O(¹D). The data show clear evidence of an asymmetrical behavior of the ionosphere between times when the F layer is descending and times when it is ascending. This asymmetry probably reflects the effects of transport on molecular ion densities in the bottom side of the F region. Our results support a low rate for the quenching reaction between N(²D) and O. Calculations indicate that measurements of airglow surface brightnesses are relatively insensitive to the abundance of atomic nitrogen in the atmosphere.
