Would you like to help to address some of the biggest uncertainties in climate projections, do you have an established background in clouds and aerosol research and do you want to further your career in a one of the world’s leading atmospheric science institutes?
You will become a key team member of the Ice Nucleation group in Leeds who are playing a leading role in NERC’s CloudSense programme (https://cloudsense.ac.uk/). You will be responsible for making measurements of ice-nucleating particles in two international field projects within the CloudSense programme: DCMEX: (Deep convective microphysics experiment) and M-Phase (Resolving climate sensitivity associated with shallow mixed phase cloud in the oceanic mid- to high-latitudes. In both of these projects you will make use of the newly developed Portable Ice Nucleation Experiment (PINE) instrument which is a new instrument for semi-autonomously measuring the concentration of atmospheric INP.
Core to both DCMEX and M-Phase are the measurements of the number concentration of ice-nucleating particles (INPs) that become active as a function of temperature. In the absence of INPs cloud droplets can supercool to well below -35°C and the prediction of primary ice crystals on INPs can trigger a cascade of microphysical properties that can completely alter the properties of a cloud and interact with dynamics. In this position you will make measurements of INP in two distinct ways. Firstly, you will collect aerosol onto filters from the FAAM aircraft and use cold stage assays to quantify the INP spectra. Alongside this you will make use of electron microscopy to examine the size resolved aerosol composition. The second technique you will use is for long term monitoring of INP using the new PINE chamber. This instrument was developed in a collaboration between Leeds-KIT (Karlsruhe Institute of Technology) and offers an unprecedented level of automation. We intend to use it for long term measurements from the Langmuir lab for the entire 2023 summer season (in the Magdelena Mountains). Finally, you will be responsible for overseeing ground based measurements of INP at the Langmuir lab during the FAAM flights in 2022.
An important part of your job will be to interact with the CloudSense modellers in order that we make the most useful measurements possible and also to ensure that the results are used correctly.
