Mr Jonathan Elsey


High Performance Computing Research Development Officer

School of Earth and Environmental Sciences

Main Building, Room 1.56, Park Place, Cardiff, CF10 3AT


I am responsible for High Performance Computing (HPC) provision to the School of Earth and Environmental Sciences. My role particularly focuses on creation and development of software for scientists in Earth to run on HPC systems, allowing for simulations and data analysis that would otherwise be prohibitively slow to be run efficiently.

I am also responsible for several Linux systems used within the School for data storage for both modellers and users of laboratory analytical equipment. I also run various small classes and workshops on scientific computing techniques within the School, particularly in Python.

I maintain an interest in research, particularly on the interface between spectroscopy and radiative transfer, and their applications to atmospheric science and climate change.






I am a scientist by background, and have previously published on many topics relating to atmospheric radiative transfer, including the effect of aerosols and water vapour on the Earth's radiation budget and high-resolution spectroscopic measurements of the water vapour continuum and solar irradiance. I am also interested in the effect of spectroscopic processes on observations of exoplanetary atmospheres.
