We report on the measurements of telluric water vapor made with the instrument FIFI-LS on SOFIA. Since November 2018, FIFI-LS has measured the water vapor overburden with the same measurement setup on each science flight with about 10 data points throughout the flight. This created a large sample of 469 measurements at different locations, flight altitudes and seasons. The paper describes the measurement principle in detail and provides some trend analysis on the 3 parameters. This presents the first systematic analysis with SOFIA based on in situ observations.

使用 SOFIA 探测大气可沉淀水蒸气，第 I 部分，使用 FIFI-LS 测量水蒸气覆盖层

我们报告了在 SOFIA 上使用仪器 FIFI-LS 进行的大地水蒸气的测量。自 2018 年 11 月以来，FIFI-LS 在每次科学飞行中使用相同的测量设置测量了水汽覆盖，整个飞行过程中大约有 10 个数据点。这在不同的位置、飞行高度和季节创建了一个包含 469 个测量值的大样本。论文详细描述了测量原理，并提供了对 3 个参数的一些趋势分析。这是首次基于现场观测的 SOFIA 系统分析。
