We have two exciting PhD positions. Both are focused on atmospheric ice nucleating particles. These aerosol particles are of primary importance in defining the phase of clouds, which makes them extremely important for climate, but we still know too little about their sources, atmospheric dispersion and how they might change in a changing climate. The projects are:
1. Using microfluidic technology to measure and identify atmospheric ice nucleating particles
This is part of the Centre for Doctoral Training (CDT) in Aerosol Science where you spend your first year learning to become an aerosol scientist (much broader than only atmospheric science). The project is to use our new microfluidics based ice nucleating particle counter. We have also just developed a way of sorting frozen and unfrozen droplets. One of the supervisors is in Hertfordshire and they have experience in transferring aerosols into microfluidic devices, which we hope to combine with our technology with the objective of building an instrument for semi-autonomous INP measurements.
Deadline: 3rd Feb 2020
2. Measuring the atmospheric particles which make ice in clouds and climate projections uncertain
This is part of the NERC Panorama Doctoral Training Programme (DTP). The project is on making use of our new PINE expansion chamber for counting ice nucleating particles at our new Atmospheric Observatory and then using source apportionment tools to figure out where these particles have come from. We know that there is often a high concentration of biological ice nucleating particles in the mid-latitudes, but we do not yet know where they come from or how they are emitted.
Deadline: 6th Jan 2020
