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.","authors_text":"(2) USRA SOFIA, A. Krabbe (1) ((1) Deutsches SOFIA Institut, CA 94035-1000, C. Fischer (1), C.
