High Resolution D- and E-region Incoherent-Scatter Radar Observations at Sondrestrom, Greenland

该提案用于格陵兰岛Sondrestrom的D和E区域雷达研究，使用SRII和康奈尔大学人员正在现场安装的新数据采集硬件。雷达对D区和E区风研究的灵敏度将显著提高，对离子薄层研究的高度分辨率和沉降粒子电离的高度剖面图将得到提高。鉴于目前缺乏对高纬度D/E区域的任何雷达研究，并且需要了解该区域的动力学和化学，以完成该区域与整个大气耦合的全球模式，因此这项工作具有重要的科学意义。高纬度的中间层是由极光产生的成分（如一氧化氮）明显被输送到低层大气的区域。PI在使用这种雷达方面有相当多的经验，并且装备精良，可以实现预期的结果。

This proposal is for D and E region radar studies at Sondrestrom, Greenland, using the new data acquisition hardware that is being installed at the site by SRII and Cornell University personnel. The sensitivity of the radar for D and E region wind studies will be significantly increased, and better height resolution for studying thin layers of ions, and the height profiles of ionization due to precipitating particles, will be available. The work is scientifically important in view of the present lack of any radar studies of the high latitude D/E region, and the need to know the dynamics and chemistry of the region to complete global models of the coupling of that region to the atmosphere as a whole. The high latitude mesosphere is the region through which aurorally generated constituents such as nitric oxide apparently are transported to the lower atmosphere. The PI has considerable prior experience of working with this radar, and is well equipped to achieve the results anticipated.
