  7. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Observations are essential for - setting initial model conditions - comparing scenario ensembles with real development Huss et al. (2014)

  8. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Grand challenges in climate-glacier research • Climate-glacier processes • Glacier distribution • Glacier change rates • Secondary impacts About 200,000 glaciers distributed over the globe.

  10. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion

  11. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion c. 1,000 pages of documentation but not (yet) much data products!

  12. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Randolph Glacier “Inventory” Huss & Farinotti (2012)

  13. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Randolph Dataset 2.0 • Randolph Dataset • by A. Arendt et al. (2012) from different source • main purpose: global SLR modelling • vector outlines of different levels of detail and quality • limited meta-data (e.g., time stamp, elevation range, length, classification) • How to bridge to last mile to GLIMS database? WGI GLIMS Randolph DCW

  14. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion How (fast) are glaciers changing? Gardner et al. (2013)

  15. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Data sources: WGMS

  16. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Data sources: WGMS

  17. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion The Alps Data sources: WGMS, Jacob et al. 2012

  18. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Elevation changes from ICESat Gardner et al. (2013)

  19. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion Elevation changes from ICESat Kääb et al. (2013)

  20. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion • Opportunities: • High spatial resolution • Covering entire mountain ranges • Challenges: • Mountain topography • How bridging the last mile? www.dlr.de Floricioiu, Jaber and Rott (2012)

  21. intro ¦ glacier distribution ¦ glacier changes ¦ conclusion • Glaciers observations are a fundamental requirement for assessing climate change impacts on glacier hazards, runoff, and global sea level rise. • Growing number of remote sensing data have a great potential for boosting glacier monitoring but requires additional capacities at the international data centers to tap the full potential of these data and to truly link traditional methods with new technologies. • Thereto, the explicit focus of ESA’s Glaciers_cci on monitoring is highly appreciated. • Phase 2 hopefully will produceless documentation but more data products!
