This award will support the analysis of the Dynamics Explorer measurements of vertical winds made with the WATS mass spectrometer. The data would be treated to remove the effects of a slowly varying bias by analyzing the raw unaveraged data to determine the variance of the observations. Different methods for determining this variance would be explored. The purpose of this effort is to gain improved insights into the effects of vertical winds in the polar region upon the composition of the auroral thermosphere. The typically large vertical winds of the this region are believed to have major effects upon the composition as a result of the modified mixing that vertical winds will introduce. The impact of this mixing enhancement is not well understood.

该奖项将支持动力学探索者用WATS质谱仪测量垂直风的分析。 将通过分析原始未平均数据来处理数据，以消除缓慢变化的偏倚的影响，从而确定观察值的方差。 将探讨确定这一差异的不同方法。 这项工作的目的是更好地了解极地地区垂直风对极光热层组成的影响。该区域典型的大垂直风被认为对组合物具有主要影响，因为垂直风将引入改变的混合。这种混合增强的影响还没有得到很好的理解。
