PhD Studentship on " Ice microphysics from multi-frequency suites of active and passive remote sensing instruments: satellite product and numerical model validation." Supervisors: Dr. Alessandro Battaglia (University of Leicester, NCEO) Dr Christine Chiu (University of Reading, NCEO) Dr. Hartmut Boesch (University of Leicester, NCEO) Hosting institution: Department of Physics, University of Leicester, Leicester, UK Funding institutions: Department of Physics, University of Leicester, Leicester, UK & UK National Centre for Earth Observation (NCEO). Application deadline: April 30th 2017 Project description: Representation of ice clouds in numerical modelling remains problematic with global average ice water paths varying by more than an order of magnitude (0.01 and 0.2 kg/m2) between different climate models. A similar spread exists amongst remote sensing satellite estimates, which makes it difficult to improve parameterization development for global models. Multi-wavelength Doppler radars&radiometers observations promise to reduce these observational uncertainties. The Phd candidate will work at the development of a modular ice/snow microphysical retrieval (including ice water content and characteristic size) and will apply it to a gamut of observations acquired in the framework of NASA GPM (https://pmm.nasa.gov/science/ground-validation/field-campaigns) field validation campaigns (e.g. OLYMPEX, IPHEx) and of the DOE-ARM program (https://www.arm.gov/), including observations from the mobile facility in Antarctica and from the permanent facility in Barrow, North of Alaska. The retrieved microphysical parameters will be used to build climatological records of ice microphysics at specific sites that will be exploited to validate satellite products (specifically GPM and CloudSat) and numerical models. The project is relevant for the energy, flux and water cycle theme since it will provide new insight into cloud and precipitation cold processes. The climatological ice products will be used for an Earth System model evaluation. Collaborative framework: This work will take place in a broad collaborative framework in UK between the University of Leicester and the University of Reading within the research activities conducted within the UK National Centre for Earth Observation (NCEO). Eligibility: Applicants for a studentship must have obtained, or be about to obtain, a Master 2 degree or higher in sciences (mathematics, physics), if possible specialized in remote sensing and/or meteorology/climatology, and with good skills in statistics and computer programming. Good communication skills are essential too. The three-year studentship is expected to start at the beginning of October 2017 in phase with other UK-NERC DTP programs but an early start can also be granted.
