Title:   The atmospheres of giant planets in our Solar System

Abstract: Our understanding of the atmospheres of the giant planets in our Solar System has improved hugely since the 
Voyager flybys in the 70/80s. Subsequent space missions and massively improved ground-based instrumentation from 
facilities such as ESO have increasingly ‘peeled back the layers’ and have allowed us to probe the atmospheres of these 
remote, freezing worlds. Here I will review what we currently know about these well-observed atmospheres, where, unlike 
exoplanets, we have many pixels/planet, rather than many planets/pixel. I will review what we know about the 
atmospheric circulations in these atmospheres and will explore what the cold temperatures in these atmospheres means 
for photochemistry, compared with the high temperatures of ‘Hot Jupiters'; I will further explore what implications this has 
for cloud formation and identification. The largest remaining uncertainties are cloud composition (much as for exoplanets) 
and, for Uranus and Neptune (the ‘Ice Giants’), the extremely cold temperatures, which hamper measurement of 
temperature and deep composition. These uncertainties will be addressed  by future ground-based observations and 
upcoming space missions such as the James Webb Space Telescope.
