Abstract She ATM-0003171This award will provide for the continuation of mesosphere and lower thermosphere temperature and wind observations from Ft. Collins, CO. The extension of the existing 9 year database over the 5 years of this award to 14 years will make possible a detailed analysis of the long term trends in this atmospheric region, which is largely a result of the solar flux variation. Current analysis shows that there is a possibility of a small temperature change that might be a result of the anthropogenic influence arising from global change. However, at present this conclusion is only tentative as the measurement series is too short compared with the length of the solar cycle (11 years) to put this conclusion on a sound footing. Instrumental improvements will also provide for possible measurements of long terms variations of horizontal wind speed and direction as well as decadal temperature trends.

摘要 She ATM-0003171该奖项将为英国《金融时报》继续进行中层和较低热层温度和风观测提供支持。科罗拉多州柯林斯市。将该奖项的 5 年中现有的 9 年数据库扩展到 14 年，将使详细分析该大气区域的长期趋势成为可能，这主要是太阳通量变化的结果。 目前的分析表明，温度可能会出现小幅变化，这可能是全球变化引起的人为影响的结果。 然而，目前这个结论只是暂时的，因为与太阳周期的长度（11年）相比，测量序列太短，无法为这个结论奠定坚实的基础。 仪器的改进还将提供对水平风速和风向的长期变化以及十年温度趋势的可能测量。
