In 2002, Austrian climatologists founded the research platform AustroClim. Its goal is to meet the challenges that climate change poses to science and to support the necessary decisions that need to be made in the political and economic sectors and by each and every individual. This is to be achieved in an interdisciplinary approach that will provide the basis for the decision- making process. In light of AustroClim's call for a coordinated climatological research effort, and based on an initiative of the Austrian Federal Minister of the Environment, six funding partners1 commissioned the Start Project Climate Protection: "StartClim – First Analyses of Extreme Weather Events and their Impact in Austria" (StartClim2003). The BOKU - University of Natural Resources and Applied Life Sciences as representative of the AustroClim Research Platform agreed to act as the project leader for StartClim. The administrative tasks were assumed by the Federal Environment Agency. StartClim continued in 2004 by sponsoring research on "heat and drought" and is now set up as a program initiating research in climate change topics not yet established in Austria. StartClim research projects are intended to subsequently be carried farther in the framework of normal research funding or as studies commissioned by interested stakeholders.

In recent years, however, additional forms of ballistic transport have become accessible in the quasi–two-dimensional delafossite metals, whose Fermi wavelength is a factor of 100 shorter than those typically studied in the previous work and whose Fermi surfaces are nearly hexagonal in shape and therefore strongly faceted. This has some profound consequences for results obtained from the classic ballistic transport experiment of studying bend and Hall resistances in mesoscopic squares fabricated from delafossite single crystals. We observe pronounced anisotropies in bend resistances and even a Hall voltage that is strongly asymmetric in magnetic field. Although some of our observations are nonintuitive at first sight, we show that they can be understood within a nonlocal Landauer-Büttiker analysis tailored to the symmetries of the square/hexagonal geometries of our combined device/Fermi surface system. Signatures of nonlocal transport can be resolved for squares of linear dimension of nearly 100 µm, approximately a factor of 15 larger than the bulk mean free path of the crystal from which the device was fabricated. ; Publisher PDF ; Peer reviewed
