CEDAR: Geophysical Study of Mesopause Region: Completion of One Solar Cycle of Lidar Observation at Fort Collins, CO (41N, 105W)

摘要她ATM-0003171该奖项将提供继续中间层和较低的热层温度和风观测从英尺。柯林斯，CO。现有的9年数据库在本奖项的5年延长到14年，将有可能详细分析这一大气区域的长期趋势，这主要是太阳通量变化的结果。 目前的分析表明，全球变化引起的人为影响可能会造成微小的温度变化。 然而，目前这一结论只是初步的，因为与太阳活动周期的长度（11年）相比，测量系列太短，无法将这一结论建立在坚实的基础上。 仪器的改进也将提供可能的水平风速和风向的长期变化以及十年温度趋势的测量。

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.
