Influence of coherent mesoscale structures on satellite-based Doppler lidar wind measurements

Efforts to develop display routines for overlaying gridded and nongridded data sets are discussed. The primary objective is to have the capability to review global patterns of winds and lidar samples; to zoom in on particular wind features or global areas; and to display contours of wind components and derived fields (e.g., divergence, vorticity, deformation, etc.). Current considerations in support of a polar orbiting shuttle lidar mission are discussed. Ground truth for a shuttle lidar experiment may be limited to fortuitous alignment of lidar wind profiles and scheduled rawinsonde profiles. Any improvement on this would require special rawinsonde launches and/or optimization of the shuttle orbit with global wind measurement networks

2009-10 statistics derived from ILR data for the monitoring and allocation of funding in FECs

"This document describes: how we used 2009-10 Data Service learner data to inform 2011-12 funding allocations how we used 2009-10 learner data to monitor returns made to HEFCE the responses required from colleges to these monitoring processes." - Page 2

2009-10 statistics derived from HESA data for monitoring and allocation of funding

Part of series - Core funding/operations: Request for information - "This document describes the process we will use when reconciling 2009-10 data returns made to the Higher Education Statistics Agency (HESA) with other returns made to HEFCE. It also describes how we use HESA data to inform the widening participation and teaching enhancement and student success allocations, and the partial completion weighting, for 2011-12." - Cover

Poynting's theorem and energy conservation in the propagation of light in bounded media

Starting from the Maxwell-Lorentz equations, Poynting's theorem is reconsidered. The energy flux vector is introduced as S_e=(E x B)/mu_0 instead of E x H, because only by this choice the energy dissipation can be related to the balance of the kinetic energy of the matter subsystem. Conservation of the total energy as the sum of kinetic and electromagnetic energy follows. In our discussion, media and their microscopic nature are represented exactly by their susceptibility functions, which do not necessarily have to be known. On this footing, it can be shown that energy conservation in the propagation of light through bounded media is ensured by Maxwell's boundary conditions alone, even for some frequently used approximations. This is demonstrated for approaches using additional boundary conditions and the dielectric approximation in detail, the latter of which suspected to violate energy conservation for decades.Comment: 5 pages, RevTeX4, changes: complete rewrit
