  1. Environment Canada Environnement Canada • Operational Ice Monitoring Requirements Mike Manore Canadian Ice Service Meteorological Service of Canada

  2. Outline • Operational Ice Services • Information Requirements • Characteristics of Operational Data • Operational Trends • Gaps/Future Requirements

  3. Operational Ice Services - 5 Ws • Who? • primarily national meteorological agencies and/or military • sometimes research labs, maritime safety agencies • What? • 0.25  90 people • $10k  $15M • Where? • ≈ 20-25 regionally-based services – focus on national waters • exception – US National Ice Center – global ice charting mission • primary interest is marginal ice zone • When? • primarily to support navigation – seasonal temporal coverage • products - daily, weekly, bi-weekly, monthly, seasonal • Why? • publicly funded for public good objectives

  4. Operational Ice Services – Why? • Ice information to support: • marine safety • avoid ice hazards • navigate safely in ice when required • marine commerce • permit shipping where otherwise not feasible • support year-round operations, regional economic development • efficiency of ship routing, icebreaker deployments • environmental protection • reduce risk of oil spills from ship damage • numerical weather prediction • environmental knowledge • support for regulation and policy development • science, sovereignty, tourism, adventurers, ….

July - October Thule Resolute June - November Inuvik Iqaluit July - October Goose Bay Canadian Ice Service Areas of Coverage (Seasonal) Major Shipping Routes Ottawa Toronto Operational Ice Services Example - CIS Mission • Area of interest -wherever there is icein Canadian waters; • biased to shipping activity in MIZ • Tactical and strategic ice information • focus on: • ice extent • concentration • type • hazardous pressure situations December - May

  8. Ice Information Services: Socio-Economic Benefits and Earth Observation Requirements Prepared for: The Group on Earth Observation (GEO) and Global Monitoring for Environment and Security (GMES) Prepared by: The International Ice Charting Working Group With funding from: The European Space Agency, GSE Contract 17062, “The Northern View” September 2004

  9. Information Requirements for Key Ice Features(adapted from CEOS, WMO, WCRP, ESA-GMES) Optimum Future Value (Current Threshold Value)

  10. Information Requirements for Key Ice Features (cont’d) Optimum Future Value (Current Threshold Value)

  11. Characteristics of Operational Data • near-real-time • <1h – 6h delivery to analysis site; <2h – 6h delivery to ships • frequent, reliable revisit periods • wide swath or multiple sensors • all weather capability desirable • diversity of observations • microwave, optical, thermal • high resolution is desirable • ice typing requires fracture, floe shape information • many navigation hazards are < 50m in size, narrow channels • data continuity • operational satellite series (10-15+ years) • multiple satellites, operational redundancy • investment in infrastructure

  12. Operational Trends • increasing volume and complexity of data • multi-satellites, multi-channel data not manageable by human analysts • higher-resolution, coupled NWP and ice models • demand for systematic ice observations suitable for assimilation • requires validated, calibrated instruments and retrievals • convergence of sensors suitable for science and operations - NPOESS  increasing convergence of operational and science observational requirements

  13. Operational Trends • increasing international cooperation • data access and sharing • standards • nomenclature, analysis practices • data exchange and interoperability • value of operational data streams and archive • imagery and analyses • increased convergence and exploitation welcomed

  14. Gaps/Future Requirements • high-resolution - revisit and continuity • SAR follow-missions • multiple satellites for revisit and operational redundancy • high-resolution, multi-pol for iceberg detection and classification • routine data fusion/data integration products • e.g. microwave + optical/thermal, scatterometer + radiometer • resolution, temporal, and coverage differences between data types need to be handled • quantitative retrievals for model assimilation • validated algorithms + error characteristics • ice thickness • at operational scales and timeframes
