IR2、UVI Venus dayside synthesized false color image by UVI and IR2 (2016 Apr 25) No.2

A synthesized false color image of Venus using 283-nm and 365-nm images taken by UVI plus 2.02-µm (2020-nm) image taken by IR2. Images are colorized as follows: 283 nm → blue; 365 nm → green; 2.02 µm → red. In the 283 nm band observed by UVI, there is an absorption band of sulfur dioxide (SO₂). Also, there is an absorption band of an unidentified chemical substance in the 365 nm band. For example, it can be said that the amount of SO₂ is relatively low in the bluish areas in this image. On the other hand, in the 2.02 µm band observed by IR2, there is an absorption band of carbon dioxide (CO₂). The distribution of CO₂ is rather uniform, but the amount of absorption is low in places with high cloud top altitudes shown in reddish color in this image. © PLANET-C Project Team
