低层大气中湿度在短时空尺度上的极端变化，对现有观测系统构成了巨大挑战。由于湿度变化会改变大气的折射特性，进而影响电磁辐射的传播，因此可通过该特性检测湿度变化。我们证明了利用干涉仪测量商业飞机常规广播的自动相关监视-广播（ADS-B）无线电传输的折射，以获取高分辨率折射率梯度测量值的能力。ADS-B干涉测量（ADSBi）技术对因湿度变化导致的折射率梯度的小尺度时空变化敏感。我们展示了如何利用不同距离和高度的飞机所广播无线电传输的观测折射差异，实现折射率廓线的反演。
英文摘要
The extreme variability of humidity in the lower atmosphere over short spatial and temporal scales presents an enormous challenge for existing observing systems. Variations in humidity can be detected due to changes in the refractive properties of the atmosphere, which influence the propagation of electromagnetic radiation. We demonstrate the ability to retrieve high-resolution refractivity gradient measurements using an interferometer to measure the refraction of the Automatic Dependent Surveillance-Broadcast (ADS-B) radio transmission routinely broadcast by commercial aircraft. The ADS-B interferometry (ADSBi) technique is sensitive to small-scale spatial and temporal variability in the refractivity gradient due to changes in humidity. We demonstrate how the retrieval of refractivity profiles is possible exploiting the differences in the observed refraction of radio transmissions broadcast by aircraft at different distances and altitudes.
