The successful candidate will analyse available satellite observations of stratospheric and mesospheric composition to quantify observed chemical impacts of ultraviolet irradiance and energetic particle precipitation variability. The obtained results will be used to assess the representation of involved chemical processes in chemistry climate models, allowing for the identification of model biases and potential model improvements. The candidate will further explore new statistical analysis methods that account for non-linear interactions of solar and internally introduced climate variability. These advanced methods will be applied to multi-decadal climate model simulations in order to quantify the effect of solar signals on climate variables and to assess how the changing atmosphere due to increasing greenhouse gas emissions modulates the climate response to solar forcing.

The Ph.D. fellow will benefit from the long research and training experience of the Terrestrial Planetary Atmosphere's Group GAPT group, as well as from the group's extended network of international collaborators, particularly within the SPARC SOLARIS-HEPPA community. She/he will participate in international conferences and training networks with the possibility of short-term visits at recognized international research institutions. It is foreseen that fellow will participate in the Physics and Space Science Ph.D. program at University of Granada. A high level of motivation, teamwork capacity and communication skills (in English language) are expected. Experience in scientific programming and initial knowledge in data analysis and statistics are desirable.
