DESCRIPTION:Miguel Crespo Castano\nEDIC candidacy exam\nExam president: Pr
 of. Mark Pauly\nThesis advisor: Prof. Wenzel Jakob\nCo-examiner: Prof. Sab
 ine Süsstrunk\n\nAbstract\nThe retrieval of the physical properties that 
 constitute the atmosphere is a challenging task. Previous work uses 1D mod
 els for this purpose\, but they can be inaccurate due to the assumptions r
 equired. This thesis aims to improve the field by introducing 3D different
 iable models that allow a higher accuracy in the retrieved parameters. At 
 the same time\, we will design sampling strategies targeted to this specif
 ic scenario\, improving both the simulation's quality and the computed gra
 dients.\nFinally\, we will validate our method and try to demonstrate the 
 benefits of the 3D information versus the 1D approximation\, potentially t
 argeting future satellite design toward being used for 3D retrievals of th
 e Earth's atmosphere.\n\nBackground papers\n\n	Mayer\, B. "Radiative trans
