Dr. Robyn Millan, Assistant Professor of Physics and Astronomy, Dartmouth College, Radiation Belt Electron Losses and BARREL "The flux of relativistic electrons in the radiation belts is known to be highly variable, but the processes responsible for this variability are not well understood. In addition to large increases in the flux often observed, rapid drops of the flux also occur, suggesting losses play an important role. In fact, observations from both balloon and satellite measurements indicate strong losses that could empty the radiation belts in a day or less if no acceleration was taking place. Thus, quantifying losses and understanding loss processes is an important part of fully understanding radiation belt variability. Balloon-based observations provide a method for studying relativistic electron losses through the observation of bremsstrahlung X-rays produced as the electrons precipitate into the atmosphere. Since balloons measure precipitation directly, such observations allow us to separate the effects of acceleration and loss. In addition, balloons offer a nearly-stationary platform from which the spatial scale, duration, and temporal variations of precipitation can be measured. This talk will first review our current state of understanding of relativistic electron loss processes. Results from several balloon campaigns aimed at studying relativistic electron precipitation will be discussed. Finally, an overview of the BARREL mission of opportunity will be provided."""

Prof. Rene' Laprise, University of Quebec at Montreal. TENETS AND ISSUES IN REGIONAL CLIMATE MODELLING "Nested regional climate models (RCMs) are increasingly used for climate-change projections in order to achieve spatial resolutions that would be computationally prohibitive with coupled global climate models. RCMs are commonly thought to behave as a sort of sophisticated magnifying glass to perform dynamical downscaling, which is to add fine-scale details upon the large-scale flow provided as time-dependent lateral boundary condition. Regional climate modelling is a relatively new approach, initiated less than twenty years ago. The interest for the approach has grown rapidly as it offers a computationally affordable means of entering into appealing applications of timely societal relevance, such as high-resolution climate-change projections and seasonal prediction. There exists however a need for basic research aiming at establishing firmly the strengths and limitations of the technique. This presentation synthesises the results of a stream of investigations by my team on the merits and weaknesses of the nested approach. It revisits some commonly accepted notions amongst practitioners of regional climate modelling, in the form of four tenets that will be challenged: (1) RCMs are capable of generating small-scale features absent in the driving fields supplied as lateral boundary conditions; (2) The generated small scales have the appropriate amplitudes and statistics; (3) The generated small scales accurately represent those that would be present in the driving data if it were not limited by resolution; (4) In performing dynamical downscaling, RCMs operate as a kind of sophisticated magnifying glass, in the sense that the small scales that are generated are uniquely defined for a given set of LBC. From the partial failure of last two tenets emerges the notion of internal variability, which has often been thought to be negligible in one-way nested models due to the control exerted by the imposed lateral boundary conditions. A fifth tenet is also discussed, relating to the handling within the RCM domain of the large scales used to drive the RCM at the LBC."

U-M alum, astronaut James McDivitt. McDivitt, who flew in Gemini and Apollo missions, will discuss his career as an astronaut and present an Astronaut Scholarship Foundation award to Civil and Environmental Engineering graduate student Heather Muñoz. Muñoz, captain of the Concrete Canoe Team, is studying structural advancements in civil engineering.
