  We report a model study on the effects of clouds on emission spectra of
super-Venus planets. Our goal is to assess possible ways to identify
characteristic spectral features due to clouds. We show that it is possible to
distinguish an impact of H2SO4 clouds on the CO2 absorption band at 4.8 micron
for temperature profiles with and without a thermal inversion. The thermal
inversion can help to distinguish the signal from high altitude clouds (85 km,
~1 mbar). Featureless emission spectra are found for high altitude clouds (85
km, ~1 mbar) with temperature profile without thermal inversion. More spectral
features appear in the emission spectra with decreasing cloud top altitudes.
The compactness of clouds has an inverse effect on emission spectra than cloud
top altitudes. Small cloud scale heights reduce the signal and the CO2
absorption bands become flat.
