Applications are invited for a Research Associate/Senior Research Associate position to study the atmosphere of Titan using mid-infrared spectroscopic data. The successful applicant will study seasonal changes in Titan’s complex atmosphere using data from the Cassini spacecraft’s Composite InfraRed Spectrometer (CIRS), which is sensitive to stratospheric composition and temperature. The project may also involve data from Cassini’s other remote sensing instruments, ground-based and space-based telescopes, and numerical models to allow more complete interpretations. The PDRA will be part of the geophysics group in the University of Bristol’s School of Earth Sciences and be working under the planetary formation, structure, and dynamics theme. The post is initially for 2 years with a possible extension to 3 years, subject to funding.
