Partner 11 - NERSC (Norway)
Nansen Environmental and Remote Sensing Center (NERSC)

Expertise and experience of the organization
NERSC is an independent non-profit research institute affiliated with the University of Bergen, Norway. NERSC conducts basic and applied environmental research funded by governmental agencies, research councils and industry. NERSC's research strategy is to integrate the use of remote sensing and field observations with local-, regional- and global-scale numerical modelling. NERSC staff teaches university courses and hosts graduate students and postdoctoral fellows from several nations. Faculty members at the Univ. of Bergen and senior staff at Nansen Center hold adjunct positions at the two institutions. NERSC is organized in 5 scientific units: Special Projects; Mohn-Sverdrup Center for Global Ocean Studies and Operational Oceanography; Coastal and Ocean Remote Sensing; Polar and Environ. Remote Sensing; G.C. Rieber Climate Institute. NERSC is a head institution of the Nansen Group, which includes establishments in Russia (Nansen Centre in S.-Petersburg), China (Nansen-Zhu Centre), India, South America and Africa to provide an impetus for globally-oriented research in support of sustainable development of the earths resources. In 2005, NERSC was awarded the prestigious European Descartes Prize for the best integrated research.

Role and contribution

In this project NERSC will be the co-leader of WP2 and the leader of its Task 4 – urban atmospheric boundary layer features, simulation, and parameterization. The primarily tools in operation will be turbulence-resolving models, namely, the NERSC LES code and parallelized LES code of the Meteorological Institute at Hannover University. With these tools, NERSC will contribute in understanding and simulations of the Paris plume (WP3) and the development of improved UABL parameterizations for WP4-6. Ultimate contribution will aim at representation of the urban climate and pollution through a 3D visualization of urban atmospheric dynamics in WP7.

Principal personnel involved
Dr. Igor Esau – is a staff member of NERSC since 2003. He has graduated Tomsk University with honour degree in 1992 and defended two Ph.Ds.: one in the area of numerical mathematics in 1996 at the Russian Institute for Numerical Mathematics, Moscow; and another in the area of turbulence modelling in meteorology in 2003 in Swedish Uppsala University, Uppsala. Dr. Esau is currently working in the area of application of the turbulence-resolving modelling to studies of local climate forming processes, especially over heterogeneous surfaces similar to urban heat islands. This project is just a natural continuation of his long-term research priorities and sevrbulence-resolving modelling. He is currently supervising 2 Ph.D. programmes. He has published 21 peer-review articles, of which 16 during the last 5 years.
