本文报道了2011年至2012年南极戴维斯站(69°S)中层顶区铁密度、温度和冰粒产状的常见体积测量结果。我们的观测表明，夏季铁层时间的耗竭与温度有很强的相关性，但与以夜光云(NLC)或极地中间层夏季回波(PMSE)衡量的冰粒的开始或发生没有明显的因果关系。这些测量结果的结合表明，夏季的强烈枯竭可以仅用气相化学来解释，不需要在冰粒上异相去除铁及其化合物。
We report common volume measurements of Fe densities, temperatures and ice particle occurrence in the mesopause region at Davis Station, Antarctica (69°S) in the years 2011–2012. Our observations show a strong correlation of the Fe-layer summer time depletion with temperature, but no clear causal relation with the onset or occurrence of ice particles measured as noctilucent clouds (NLC) or polar mesosphere summer echoes (PMSE). The combination of these measurements indicates that the strong summer depletion can be explained by gas-phase chemistry alone and does not require heterogeneous removal of Fe and its compounds on ice particles.
