iLEAPS Scientific Steering Committee (SSC)

The iLEAPS Scientific Steering Committee (SSC) members are scientists selected from the international environmental research community. New iLEAPS SSC members are appointed by the Scientific Committee of IGBP (SC-IGBP) on the basis of their scientific expertise and serve for a period of three years with the possibility of one renewal period. The SSC guides the overall direction and development of the project by:

  • Providing scientific guidance to and oversee the development, planning and implementation of iLEAPS
  • Encouraging the promotion and wide awareness of iLEAPS amongst science communities including publication of results.
  • Demonstrating progress and achievements by defining and monitoring milestones and results.
  • Encouraging national governments, regional and international funding agencies to support the implementation of iLEAPS and the achievement of it's goals by providing adequate support to the necessary national, regional and international research.
  • Encouraging collaboration between iLEAPS and other International Programmes and Agencies concerned with the scientific study and assessment of global change.

Past iLEAPS members

Current iLEAPS members

Prof. Dr Hans-Christen Hansson (co-Chair)

Hans-Christen Hansson is professor in Air pollution and head of the Department of Applied Environmental Science (ITM). His present work within mostly larger projects is directed towards investigations of the life cycle of the atmospheric particles, especially how atmospheric particles influence the radiation budget, both directly through scattering of radiation and indirectly through their influence on the clouds and their effect on the radiation balance. Influence on health is a growing concern, which drives his involvement connecting urban research with the regional focused research. A growing substantial effort is now on implementing all achieved knowledge on processes in dynamic transport models giving a possibility describing parameters important to climate and health with high resolution spatially and temporally both on regional as well as urban scale. HC Hansson was one of the founding partners in the NCoE BACCI as well as major EU projects as EUCAARI and EUSAAR.
