Title: Atmospheric thermal structure and cloud features of Venus as retrieved from VIRTIS/VEX measurements
Abstract: Updated results on mesospheric nightside thermal
structure and cloud features of Venus are presented
that were retrieved from VIRTIS-M-IR measurements
during eight Venus solar days between
April 2006 and October 2008 using new methodical
approaches. Maps for the southern hemisphere cover
parameter variations with altitude, latitude, local time,
and mission time. The mesospheric temperature field
strongly depends on latitude and local time. Zonal
averages of retrieved temperature profiles and cloud
parameters in both hemispheres show global N-S
axial symmetry. Cloud top altitude at 1 μm decreases
from 71 km at the equator to 61 km over both poles.
Average cloud particle size is minimal at mid latitudes
