Quick Look: The Thermal Structure of the Venus Atmosphere


For two years beginning in 2013, a large team led by Sanjay Limaye set out to combine and compare the following:
  • Venusian atmospheric data collected by probes in the 1970s and 1980s (used to create the Venus International Reference Atmosphere, or VIRA)
  • Venus Express data on the vertical and horizontal structure of the atmosphere
  • Earth-based observations of the upper atmosphere temperature structure of Venus made since VIRA

This work is seen as the first step toward creating an updated VIRA model. You can read it here.
