Open position for a PhD student (IMK-IFU01-08) Forschungszentrum Karlsruhe GmbH is one of the largest natural science and engineering research institution in Europe. Our Atmospheric Environmental Research Division (IMK-IFU) of the Institute for Meteorology and Climate Research has a long tradition in atmospheric environmental research, with its main emphasis on studying the impact of anthropogenic activities on the interactions between atmosphere and biosphere, air quality, regional climate, and hydrology. Studies in these research fields are characterised by an interdisciplinary and integrated approach involving field measurements, process studies and numerical modelling. Results obtained in these research fields are used for defining reliable and efficient mitigation and adaptation strategies. For numerical modelling tasks within the project “Verification of the turbulence parameterization and the description of the vertical structure of the marine atmospheric boundary layer in numer...
