Photochemistry of the Middle Atmospheres of Venus and the Earth. Ongoing changes in the Earth's atmosphere, such as ozone depletion, demonstrate the need to understand the processes that control atmospheric chemistry. The proposed research will improve the fidelity of photochemical models, provide additional insight into the recent evolution of the Venus atmosphere, and examine how atmospheric chemistry and climate change interact(ed) on Venus.

Ongoing changes in the Earth's atmosphere, such as ozone depletion, demonstrate the need to understand the processes that control atmospheric chemistry. The proposed research will improve the fidelity of photochemical models, provide additional insight into the recent evolution of the Venus atmosphere, and examine how atmospheric chemistry and climate change interact(ed) on Venus. This research will improve our understanding of long-standing issues, such as how much water might have been present on Venus in the recent past. The research program will provide an opportunity for Australian science to participate in at least one spacecraft mission to Venus. Read moreRead less
