Abstract

The oxygen spectrometer for atmospheric science on a balloon (OSAS-B) is the first 4.7-THz heterodyne spectrometer on a stratospheric balloon. It has been developed for remote sensing of the 4.7-THz emission of neutral atomic oxygen in the mesosphere and lower thermosphere of the Earth. OSAS-B comprises a heterodyne receiver based on a hot-electron bolometer mixer and a quantum-cascade laser as local oscillator. The high sensitivity of the superconducting detector and the large resolving power of approximately

$1\times 10^{7}$

enable the detection of subtle signatures of radiation transport and high-altitude winds in the measured spectra. The first flight of the instrument took place on September 7th, 2022 from Esrange, Sweden.

OSAS-B：高层大气原子氧气球式太赫兹光谱仪

气球上的大气科学氧分光计（OSAS-B）是第一个安装在平流层气球上的 4.7-THz 外差分光计。它是为遥感地球中间层和低温层中性原子氧的 4.7-THz 发射而开发的。OSAS-B 包括一个外差接收器，该接收器基于一个热电子振荡器混频器和一个作为本地振荡器的量子级联激光器。超导探测器的高灵敏度和大约 1/times 10^{7}$ 的高分辨率使得能够在测量到的光谱中探测到辐射传输和高空风的微妙特征。该仪器于2022年9月7日在瑞典埃斯朗日进行了首次飞行。
