dc.description.abstractThe plan which gave purpose to this thesis was purposefully ambitious. Instead of focus-sing on a single theme, we chose to follow a path that would ultimately lead to a greater overall understanding of several ongoing processes within the atmospheres of planets in the Solar System. Our goal was to combine different techniques in a single project so that by the end of this PhD, not only did the candidate obtain valuable results and a worthy contribution to the scientific community, but also became proficient in multiple ways to study planetary atmospheres. With images from multiple spacecraft, we employed the Cloud-Tracking technique to study the winds on multiple layers of Venus’cloud deck, and at the tropospheric level of Jupiter’s atmosphere. We used the most modern instruments such as those on board the japanese Akatsuki mission, retrieving multiple wind profiles to study the variability and evolution of the atmosphere across several altitude layers. Along with capturing winds, we set out to gather the most complete survey of atmospheric gravity waves on the lower clouds of Venus. This effort will help not only to understand their role in powering su-perrotation but also provide general circulation models valuable data on this previously under-explored feature. From the ground we performed a unique Doppler velocimetry method to complement our analysis, proving that the wind results obtained from this method can be competitive with those gathered from spacecraft data at significantly lower costs and greater flexibility. The capabilities of the team in which I am inserted have enabled multiple collaborations on other projects, further reinforcing that science is a joint effort. In this document, I attempt to provide further proof that my contribution is not only to academia but the larger society as well.pt_PT
