Complex Aerosol Experiment in Western Siberia (April – October 2013)

The primary project objective was to accomplish the Complex Aerosol Experiment, during which the aerosol properties should be measured in the near-ground layer and free atmosphere. Three measurement cycles were performed during the project implementation: in spring period (April), when the maximum of aerosol generation is observed; in summer (July), when atmospheric boundary layer height and mixing layer height are maximal; and in late summer – early autumn (October), when the secondary particle nucleation period is recorded. Numerical calculations were compared with measurements of fluxes of downward solar radiation. It was shown that the relative differences between model and experimental values of fluxes of direct and total radiation, on the average, do not exceed 1% and 3% respectively

Electronic structure and excitations on clean and nanostructured metal surfaces

11 páginas, 11 figuras.We present a brief overview of recent studies and new theoretical results for electron-phonon interaction in the [`(Y)]Y surface states on FCC(110) noble metal surfaces as well as in surface and quantum-well states of thin films. We discuss the oscillations of electron-phonon coupling parameter λ and the respective contribution to the lifetime broadening of these states. We analyse the effect of spin-orbit splitting of surface states on an electron-electron contribution to lifetimes of excited electrons (holes). Oscillations of the electron-electron contribution and quadratic dependence of the linewidth on energy is discussed for ultrathin Pb(111) films.We gratefully acknowledge partial support by the Department of Education of the Basque Country Governement, the University of the Basque Country (project GV-UPV/EHU, grant IT-366-07), and Ministerio de Ciencia y Tecnología (grant FIS2007-66711-C02-01).Peer reviewe
