PhD (m/f) on "Airborne measurements of the phase composition of high-latitude mixed-phase clouds"

Mixed-phase clouds remain one of the greatest source of uncertainties in understanding the high latitude response to the climate change. This is in particular due to an inaccurate representation of the cloud composition in terms of relative number fractions of ice and liquid particles (phase composition). In this project we seek a PhD candidate to investigate the phase composition of high-latitude (Arctic and Southern Ocean) mixed-phase clouds using a novel airborne measurement technique. This technique is based on measurements of single particle angular scattering function and analysing the shape of this function for phase discrimination.

Tasks in the project include

Development of an algorithm that discriminates between ice and liquid particles based on the shape of their angular scattering function
Participation to international measurement campaigns, including the SOCRATES campaign based in Hobart, Tasmania, in Jan/Feb 2018
Analysis of datasets from participated field campaigns and from previously conducted arctic campaign, ACLOUD
International co-operation with other instrument teams
The PhD candidate will be placed in the IMK-AAF’s research group located at KIT in Karlsruhe, Germany but is expected to participate in internal measurement campaigns lasting up to 6 weeks.

We offer the change to work with on-of-the-kind instrumentation and conduct airborne atmospheric research in international field projects. Salary and benefits will be based on the Collective Agreement for the German Public Service Sector.
