This SGER award for $30,000 supports a campaign by Boston University scientists designed to obtain daytime observations at Sondre Stromfjord, Greenland. This effort would be based upon the application of two sophisticated imaging spectrographs designed to make measurements of auroral emissions in the presence of the large Rayleigh-scattered continuum of the daytime sky. These measurements would be conducted simultaneously with the Sonderstrom radar observations of electron density profiles to obtain a determination of the ionospheric conductances in the E-region. The radar measurements of this quantity would be compared with the calculated conductance based upon a model that relates E-region electron densities to the energy of precipitating particles in aurora that would be inferred from the optical measurements. This effort would establish the feasibility of the daytime application of both optical instruments and would also take advantage of the current period of solar maximum activity.

这个SGER奖为30，000美元，支持波士顿大学科学家的一项活动，旨在获得格陵兰Sondre Stromfjord的日间观测。 这项工作将以应用两台精密的成像摄谱仪为基础，这两台摄谱仪是为了在白天天空存在大量瑞利散射连续体的情况下测量极光发射而设计的。 这些测量将与Sonderstrom雷达对电子密度分布的观测同时进行，以确定E区的电离层电导。 雷达测量的这一数量将与计算电导的基础上的一个模型，E-区域的电子密度与极光中的沉淀粒子的能量，将从光学测量推断。 这项工作将确定白天应用这两种光学仪器的可行性，并将利用目前太阳活动最活跃的时期。
