These profiles were retrieved from the infrared spectra acquired by the Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft. The retrieval method and the description of the used dataset are detailed by Vinatier et al. (2010), and completed in Mathé et al. (2020), and Vinatier et al. (2020).
