Thermal profile of Venus at low latitude used in the calculations. Thick black line: Nominal profile, which provides the best fit for the integrated spectrum shown in Fig. 2. With a cloud level at 62 km (T = 231 K), it also fits the 7-μm data of October 2012. Blue: thermal profile retrieved at the equator from the VIRTIS-M CO data at 4.7 μm (Irwin et al. 2008). Magenta: VIRA thermal profile at the equator (Seiff et al. 2005). Green: VeRa profile obtained near the equator (Lee et al. 2012; Piccialli et al. 2012).
