Venus’ upper haze was observed at 70–95 km by SPICAV IR.
Detached haze layers were detected at altitudes from 70 to 90 km.
The aerosol scale height equals to 3.3 ± 0.7 km.
Particle size and number density profiles for bimodal and unimodal cases are retrieved.
Unimodal radius equals 0.54 ± 0.25 μm and is smaller in the polar region than in nonpolar regions.
