A short history of DUE Permafrost
 ESA Expert Consultation Workshop at AWI in February
2008
– to define permafrost indicators which are observable from space,
– to describe opportunities for trend analyses from data archives (Earth obs and in
situ),
– to generate a strategy for present Earth observation capabilities, and
– to develop recommendations for a future permafrost monitoring programme.
 Call for user commitment letters in summer 2008
 Call with statement of work based on the expert
workshop by ESA in Autumn 2008
 Project start in June 2009, duration 30 months ( end of
2011)
DUE PERMAFROST
2nd User Workshop
Project objective
 Identification and assessment of permafrost relevant
Earth Observation products and provision to permafrost
scientists
 A monitoring system on mostly existing remote sensing
products is established
 Supporting
– The GCOS implementation plan
– National and intergovernmental bodies
– Scientific groups involved in climate change research

2nd User Workshop
Survey
 Diverse
– scale requirements
– Areas of interest
– technical specifications
Panarctic/boreal
Regional
Local
DUE PERMAFROST
• As input for
permafrost and
climate modelling
• Regional modelling
• Scaling
• Field investigations
• Assessment of
regional to pan-scale
service
2nd User Workshop
Observation Strategy
 First time presented at the 1st user workshop
 Multiscale concept
– Pan-boreal/arctic (> 50° N): 25 km
• Regional (1.5 mio km²): 150m - 1 km
– Local (> 20.000 km²): as available
 Pan-boreal/arctic service based entirely on existing
remote sensing products. Product improvement
through sensor fusion and adaptation to high latitude
requirements
 Regional service adjusted existing products and new
products based on existing algorithms
 Local service in cooperation with users and for coarse
level products assessment
