Purpose and rationale

The objective of ICCC is to support science driven questions of high interest to society, science, industry and/or national infrastructure.

All Nordic countries are effected by the Cryosphere

IPCC models performs badly for the Cryosphere

Important for industries like hydropower, forestry, fishing, transport, exploration and tourism

Nordic Cryosphere research is in many ways world leading

Support to ICCC NCoE

Project duration is five years (3+2)

Funding covers:

  • Support to researcher and key staff

  • Fellowships for visiting professors

  • Fellowships for post docs

  • Fellowships for PhD students

  • Nordic research schools (research training)

  • Equipment

  • Travel, management and co-ordination

Objectives of CRAICC – Cryosphere-Atmosphere Interactions in a Changing Arctic Climate

  • Role of short-lived climate forcing agents - SLCF

  • Identify and quantify the major processes controlling Arctic warming and related feedback mechanisms and to outline strategies to mitigate Arctic warming

  • Develop Nordic Earth System modelling

  • Supradisciplinary knowledge transfer

Objectives of DEFROST

  • To improve our understanding of Arctic terrestrial and shallow sub-sea permafrost interactions with climate

  • To provide improved data on energy exchange, carbon cycling and GHG emissions from terrestrial and near coastal cryospheric environments

  • To improve on climate model capabilities for simulating the feedback processes associated with observed changes in permafrost, snow and ice

Objectives of SVALI – Stability and Variations of Arctic Land Ice

  • A comprehensive joint Nordic research programme to study basic processes (flux of meltwater and icebergs from glaciers)

  • Using remote sensing, airborne and in-situ measurements

  • Carry out advanced Earth system Modelling

  • Focus on glaciers in the Arctic /N-Atlantic area.

  • Establish a Nordic graduate school in cryosphere science and Earth System modelling

Features of the centres in the NCoE programme

  • Each NCoE has partners from all five Nordic countries, one including Greenland

  • The NCoE programme has participation from the other Arctic countries (Russia, USA, Canada) and the UK

  • Each NCoE has about 17 partners

  • The NCoE programme involves about 340 researchers

  • Open data policy within and between NCoE’s
