Abstract

The detection of phosphine (PH3) in the atmosphere of Venus has been recently reported on the basis of millimetre-wave radio observations and their reanalyses. In this Matters Arising we perform an independent reanalysis, identifying several issues in the interpretation of the spectroscopic data. As a result, we determine sensitive upper limits for PH3 in Venus’s atmosphere (>75 km, above the cloud decks) that are discrepant with the findings.
