AST-0805540NovakThis project will study the Martian atmosphere by (1) mapping ozone diurnally and latitudinally above and below 20 km; (2) mapping HDO and H2O diurnally and latitudinally; and (3) searching for trace species and undiscovered absorption (or emission) bands in the one to five micron range. It will provide useful scientific information both for modeling the Martian atmosphere and for future space missions. Current work has measured ozone in the middle atmosphere (20-50 km) and this study will complement those values by measuring the total column density of ozone, thus giving insight into the vertical distribution of the gas. New Deuterium-to-Hydrogen ratio (D/H) measurements will add a diurnal component to existing values taken along the sub-Earth meridian of Mars. Data will come primarily from CSHELL on the NASA IRTF, Phoenix on Gemini South and SOAR, and NIRSPEC on Keck II.An integral part of this research is to engage undergraduate students, who reduce and analyze data, participate in observing runs, and present their findings at meetings. The project will be conducted at Iona College, an undergraduate institution, but with wider exposure through collaborators at the NASA Goddard Space Flight Center. Talks given to meetings on undergraduate education and to local community groups will incorporate the results.

该项目将研究火星大气，方法是：（1）绘制20公里以上和以下的臭氧日图和纬度图;（2）绘制HDO和H2O日图和纬度图;（3）寻找1至5微米范围内的痕量物质和未发现的吸收（或发射）带。 它将为火星大气建模和未来的太空任务提供有用的科学信息。 目前的工作是测量中层大气（20-50公里）中的臭氧，本研究将通过测量臭氧总柱密度来补充这些数值，从而深入了解气体的垂直分布。 新的氘氢比（D/H）测量将在现有的沿火星地下子午线沿着测量的值上增加一个昼夜分量。 数据将主要来自美国宇航局IRTF上的CSHELL，双子座南部和SOAR上的凤凰号，以及凯克II上的NIRSPEC。这项研究的一个组成部分是吸引本科生，他们减少和分析数据，参与观测运行，并在会议上展示他们的发现。 该项目将在本科院校艾奥纳学院进行，但通过美国宇航局戈达德太空飞行中心的合作者进行更广泛的接触。 在本科生教育会议和地方社区团体上的演讲将纳入结果。
