Fig. 3From: An uppermost haze layer above 100 km found over Venus by the SOIR instrument onboard Venus ExpressThe latitudes of selected SOIR occultations are plotted as a function of the VEX orbit number. The corresponding first days of each Earth year are given at the top of the figure. The dots (●) are for morning solar occultations, while the crosses (×) are for evening solar occultations. There is one orbit per Earth day. There are 128 occultations considered in this work. The data cover the period from 2006 to 2010Back to article page
