Research Fellow in Atmospheric Ice Nucleation

This role will be based in the School of Earth and Environment, with scope for it to be undertaken in a hybrid manner. We are also open to discussing flexible working arrangements., INPUT:ACCESS will develop the capability for routine measurement of upper tropospheric water vapor concentration, (INP) concentrations and cirrus crystal profiles using balloon-borne instruments. This innovative approach will facilitate evaluation of cirrus-related climate interventions by determining INP characteristics within the context of aerosol populations and air mass conditions. To do this NOAA will develop a balloon-borne INP collector and cirrus ice crystal counter and will conduct a campaign of weather balloon launches to collect INPs from the upper troposphere. The successful candidate will be responsible for building and using an isothermal diffusion chamber capable of exposing collected INPs to cirrus cloud conditions to determine INP concentrations in the upper troposphere.

Would you like to help understand the feasibility of climate cooling approaches that might "buy time" to decarbonise? Do you have an established background in experimental cloud and aerosol research, and do you want to further your career in a one of the world's leading atmospheric science institutes? We are seeking a highly motivated and skilled Postdoctoral Research Fellow to join our team in the exciting field of Atmospheric Ice Nucleation. The successful candidate will play a pivotal role in building, developing and using a new isothermal diffusion chamber for measuring ice nucleation particle (INP) concentrations in the upper troposphere. This project is a collaborative effort between the University of Leeds, the National Oceanic and Atmospheric Administration (NOAA) and Imperial College London. You will become a key member of the Ice-Nucleating Particles in the Upper Troposphere: Advancing Cirrus Control and Experimental Science Strength (INPUT:ACCESS) team focused on quantifying the concentration of ice-forming particles present in the upper troposphere (UT). This job is part of an Advanced Research + Invention Agency-funded project, subject to contract negotiations. Background: Water vapor and cirrus ice clouds in the upper troposphere significantly impact Earth's radiation balance by trapping long-wave radiation. Three proposed methods aim to reduce global climate forcing by manipulating upper tropospheric/lower stratospheric water vapor and cirrus clouds: cirrus cloud thinning (CCT), contrail management (CM), and intentional stratospheric dehydration (ISD). However, these methods depend on poorly understood climate phenomena, and current models and measurements are inadequate to ensure their effectiveness.
