This proposal is for a continuing program of ground-based millimeter wave spectroscopic measurements of trace gases in the earth's mesosphere and lower thermosphere (MLT), using existing astronomical receivers at Kitt Peak National Radio Astronomy Observatory (NRAO). The millimeter observations of mesospheric water isotope ratios provide unique diagnostics to investigate the signatures vertical transport of hydrogen-bearing species from above and below the mesosphere may force in the vertical profiles, as well as D/H ratios, of mesospheric water. The millimeter observations support SNOE and TIMED spacecraft observations.

该提案是一个基于地面的毫米波光谱测量地球中间层和低层热层（MLT）中微量气体的持续项目，使用基特峰国家射电天文台（NRAO）现有的天文接收器。对中间层水同位素比值的毫米级观测为研究含氢物质从中间层上方和下方垂直输送可能迫使的特征以及中间层水的D/H比值提供了独特的诊断方法。毫米观测支持SNOE和TIMED航天器观测。
