The in situ measurements of the Galileo Probe Mass Spectrometer (GPMS) were expected to constrain the abundances of the cloud-
forming condensible volatile gases: H2O, H2S, and NH3. However, since the probe entry site (PES) was an unusually dry meteorological
system--a 5-m hotspot--the measured condensible volatile abundances did not follow the canonical condensation-limited vertical profiles
