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.

该奖项将支持对用WATS质谱仪制成的垂直风的动力学探索器测量值的分析。 通过分析原始的非平衡数据来确定观测值的方差，将处理数据以消除缓慢变化的偏差的效果。 将探索确定此方差的不同方法。 这项工作的目的是改善对极性区域垂直风对极光热层组成的影响的见解。人们认为，由于垂直风将引入的修改混合，该区域的垂直风通常对组成产生了重大影响。这种混合增强的影响尚不清楚。
