POWRE: Small-scale Atmospheric Waves Observed with the Global Positioning System

本研究的目的是验证由全球定位系统数据的掩星方法得出的大气温度观测结果。从GPS数据获得的温度曲线显示，在10公里至60公里的高度上有大幅度的振荡。首席研究员将与澳大利亚阿德莱德大学的同事合作开展一个项目，将气象气球的高分辨率探测数据与全球定位系统的数据进行比较，以确定温度波动是否真的是大气波的指标。如果这些是真正的波，GPS数据提供了一个在全球范围内监测这种波的机会。我们了解这些波浪很重要，因为它们对气候和全球环流有潜在的影响。

The objective of this research is to validate observations of atmospheric temperature derived by occulation methods from data from the Global Positioning System. Temperature profiles obtained from the GPS data show large-amplitued oscillations at heights between 10 km and 60 km. The principal investigator will collaborate with colleagues at the University of Adelaide in Australia on a project to compare high-resolution sounding data from weather balloons with the data derived from the GPS to determine whether the temperature oscillations are truly indicators of atmospheric waves. If these are truly waves, the GPS data provide an opportunity to monitor such waves globally. It is important that we understand these waves because of their potential effects on climate and global circulation.
