The PI intends to improve basic understanding of the climatology (long term variations) of the F-region ionosphere. He will perform a detailed analysis of the seasonal and solar cycle variations of the ionospheric peak electron density, primarily to determine the reasons for the density variation as a function of solar activity. Better ionospheric models, important for both military and commercial applications, will improve capabilities of over-the-horizon radar. The PI will study causes of the observed density variation with an innovative theoretical ionosphere model, known as the FLIP model, which is capable of utilizing three key ionospheric measurements as constraints.

PI计划旨在提高对f区电离层气候学（长期变化）的基本认识。他将对电离层峰值电子密度的季节和太阳周期变化进行详细分析，主要是为了确定密度变化作为太阳活动函数的原因。更好的电离层模型对军事和商业应用都很重要，将提高超视距雷达的能力。PI将利用一种创新的理论电离层模型，即FLIP模型，研究观测到的密度变化的原因，该模型能够利用三个关键的电离层测量作为约束。
