Abstract : In this paper we present initial results of the nadir data processing from two spectrometers that measured UV albedo of Venus clouds onboard the Venus Express (VEX) orbiter in 2006-2014. The UVchannel of SPICAV operated in the range of115-320 nm [7], while the UV-VIS channel of VIRTIS covered the range of 300-1000 nm [8].We have selected a few tens of simultaneous nadir observations of Venus clouds with similar pointing that allows us combining theclouds reflectancespectra at 200-600 nmusing datasets from two spectrometers
