Description

We have re-processed ALMA observations of Venus from 2019, making a better line/continuum data-product for PH3 absorption. We test the outputs against hypotheses that (a) PH3 could be a by-product of active volcanism, or (b) phosphine production turns on within the high atmosphere in sun-light. The latter result might support the arguments for extant micro-organisms in the clouds of Venus.
