# Phosphine in the Venusian Atmosphere: A Strict Upper Limit From SOFIA GREAT Observations

M. A. Cordiner, G. L. Villanueva, H. Wiesemeyer et al., 2022. _Geophysical Research Letters 49(22), e2022GL101055_.

Three SOFIA flights in November 2021 targeted phosphine lines near 533 and 1,067 GHz and found none; radiative transfer gives a disk-averaged upper limit of 0.8 ppb from 75 to 110 km.
