我们从极地大气中的气球观测中恢复了由高能电子沉淀引起的大气中的电离率，并将它们与耦合模式相互比较项目第六阶段建议的电离率进行了比较。在我们的恢复过程中，我们考虑了能量从几十keV到5 MeV的沉淀电子。我们用一维辐射对流模式和中性离子化学相互作用进行的模拟表明，耦合模式比对计划的第六阶段和基于气球的电离率的不同可能导致对中间层NOx增强的低估超过100%，臭氧损失高达25%。由于考虑了高能电子，50公里以下的大气响应有所不同，但这并不重要，因为大气影响的绝对值很小。从气球观测获得的电离率显示出很高的可变性。
We retrieve ionization rates in the atmosphere caused by energetic electron precipitation from balloon observations in the polar atmosphere and compare them against ionization rates recommended for the Phase 6 of the Coupled Model Intercomparison Project. In our retrieval procedure, we consider the precipitating electrons with energies from about tens of keV to 5 MeV. Our simulations with 1‐D radiative‐convective model with interactive neutral and ion chemistry show that the difference of the Phase 6 of the Coupled Model Intercomparison Project and balloon‐based ionization rate can lead to underestimation of the NOx enhancement by more than 100% and ozone loss up to 25% in the mesosphere. The atmospheric response is different below 50 km due to considering highly energetic electrons, but it is not important because the absolute values of atmospheric impact is tiny. Ionization rates obtained from the balloon observations reveal a high variability.
