次声记录可用作反演程序的输入，以描绘某一高度范围内的温度和风的垂直结构，在这些高度，地面或卫星测量很少，而且目前的大气规范不能分辨细小尺度的大气结构。由于次声是在全球范围内测量的，这使得可以在全球范围内应用的遥感技术成为可能。本章概述了最近发展起来的次声遥感方法。这些方法的范围从线性化反演到直接搜索法以及大气次声的干涉技术。对数值天气预报(NWP)产品的评估显示了次声的附加值，例如在平流层突然变暖(SSW)和春分期间。讨论了数值天气预报模式中次声同化的可能过渡。
Infrasound recordings can be used as input to inversion procedures to delineate the vertical structure of temperature and wind in a range of altitudes where ground-based or satellite measurements are rare and where fine-scale atmospheric structures are not resolved by the current atmospheric specifications. As infrasound is measured worldwide, this allows for a remote sensing technique that can be applied globally. This chapter provides an overview of recently developed infrasonic remote sensing methods. The methods range from linearized inversions to direct search methods as well as interferometric techniques for atmospheric infrasound. The evaluation of numerical weather prediction (NWP) products shows the added value of infrasound, e.g., during sudden stratospheric warming (SSW) and equinox periods. The potential transition toward assimilation of infrasound in numerical weather prediction models is discussed.
