  1. The GlobGlacier project Espen Volden European Space Agency Earth Observation Science, Applications and Future Technologies Department Frank Paul University of Zurich Department of Geography

  2. The GlobGlacier project New activity within ESA’s Data User Element (DUE) programme Aim: Establish services for operational glacier monitoring from space, complementing and strengthening the existing services and network Users: Science community studying glaciers in the context of climate change Budget: 950 K€

  3. The GlobGlacier project Objectives • Products responding to • Operational needs & requirements of a certain number of users who will be actively involved in the project • Requirements of the GCOS implementation plan for UNFCCC • & GCOS "Systematic Observation Requirements for Satellite-based Products for Climate" • Priority application areas: • complementing and completing the WGI with 2D vector outlines • changes in glacier length, size, and volume • global trends of climate change and sea level rise contribution

  4. The GlobGlacier project Service extent • Total number of glaciers to be investigated will vary according to the information products: from selected mass balance glaciers to tens of thousands of glaciers worldwide • Geographical areas: glaciers from at least • Europe – Alpes • Europe – North • Africa • Asia • South-America • North America • New Zealand • Time period: • Glaciers will also be analyzed over time, going back 10-20 years.

  5. The GlobGlacier project • User requirements meetings • 22-23 June 2006, University of Zurich • 16 August 2006, Cambridge • Objectives: Define requirements for the information products to be developed and implemented in the GlobGlacier project • Output of the meeting: • A user requirements document with six products • Confirmed interest from meeting participants to participate • Document for a proposed co-operation between GlobGlacier and the GLIMS initiative

  6. The GlobGlacier project • Involved user groups: • WGMS • GLIMS • scientists (cryosphere, climate modelling, sea-level-rise) • Interested users: • GTOS/GCOS • UNESCO (GRID-Geneva) • hydrological programmes and organisations • further scientists and the general public

  7. The GlobGlacier project • Areas of interest: • Representative key regions (without the two Ice Sheets) • entire mountain ranges or massifs • several 10’000 km2 • Selection criteria for representative regions: • Climate change detection: • Include and extend available long-term in-situ measurements • Bridge geographic gaps of the world glacier inventory (WGI) also with respect to DEM coverage (outside SRTM) • include different glacier geometries (size, aspect, dynamics, …) • Sea level rise: • Large area covered, climatically sensitive region • Close coordination with GLIMS and WGMS

  8. The GlobGlacier project Products • Area: Digital map of glacier outlines + a level 2 product that can readily be ingested into the GLIMS database (including individual glaciers with topographic parameters) • Snowline: Position of the end of summer snowline (ELA) for mass balance determination • Terminus position: Coordinates of lowest glacier elevation or vector line marking the terminus • Topography: Digital map of surface elevation (DEM), both from the ice surface and outside • Elevation change: Time slices of DEMs or point elevation trends • Velocity: Velocity fields or velocities at individual points

  9. Schedule • Planned start: Summer 2007 • Duration: 3 years • Three project phases: - Definition phase (6 months) - Development phase (10 months) - Production and Validation Phase (20 months)

  10. Organization of GlobGlacier • 5 consortium partners & 5 PhDs • Universities of Zurich (lead), Oslo and Edinburgh • Gamma Remote Sensing (CH) and ENVEO (AU) • 5 work packages covering the 6 products • each lead by one of the consortium members • close interactions among the WPs • full documentation of applied standards / techniques • Close interaction with user groups • 4 user meetings in Zurich defining the requirements, testing the products, reporting about the service • advisory board provides guidelines global outreach
