IICWG Action Item 2
Identify national centre requirements for future spaceborn SAR data orders
OCTOBER 2000 IICWG-II Reykjavik, Iceland
IICWG Survey Results
9 out of 13 questionnaires were completed Response from Canada, USA, Russia, Norway,
Finland, Japan, China, Denmark, Germany
Thank you !
OCTOBER 2000 IICWG-II Reykjavik, Iceland
Present Usage of SAR
Operational users of Near Real Time ERS and / or RADARSAT dataNational Ice Center, USACanadian Ice ServiceGreenland Ice ServiceFinnish Ice ServiceSwedish Meteorological and Hydrological InstituteBSH, German Ice Service
Approximately8.000 Radarsatscenes per year
(mostly ScanSar)
OCTOBER 2000 IICWG-II Reykjavik, Iceland
Present Usage of SAR
Would like to use RADARSATNorwegian Meteorological Institute, Ice Patrol.
• Interested in using 100 - 150 scenes SCN / year
Arctic and Antarctic Research Institute, RussiaNational Research Center for Marine Environment
Forecasts, China• Interested in using 6 SCW / year
Japan Meteorological Agency• Interested in using 50 - 100 scenes per year
OCTOBER 2000 IICWG-II Reykjavik, Iceland
Future Usage of SAR
ENVISAT AO’sNational Ice Center, USACanadian Ice ServiceGreenland Ice ServiceFinnish Ice ServiceNational Research Center for Marine Environment
Forecasts, ChinaGreenland Ice Service
Approximately2.500 AO
Envisat scenes
OCTOBER 2000 IICWG-II Reykjavik, Iceland
Future Usage of SAR
ENVISAT AO’s (cont.)There is a strong wish to evaluate Envisat data in an
operational environment• Mostly ScanSAR Wide and Global Mode data will be used for
operational purposes• Alternating Polarisation data will mostly be used for research
It is anticipated that Envisat and Radarsat data in combination may provide the basis for better products
OCTOBER 2000 IICWG-II Reykjavik, Iceland
Future Usage of SAR
ENVISAT AO’s (cont..)The Envisat ground segment must be able to provide
NRT data - timeliness is crucialEnvisat will hopefully be able to fill the gab (if any)
between Radarsat-1 and 2As is the case of Radarsat high prices on Envisat data
will be a major obstacle against widespread use• Will competition lead to lower prices ?
Only a few ice services state that they intend to buy data

SAR Data Sharing
The ideas of SAR data sharing relates both to Radarsat and Envisat data
Lower prices per scene and a larger pool of data are driving forces
Legal, contractual and practical matters must be examined
OCTOBER 2000 IICWG-II Reykjavik, Iceland
SAR Data Quality
Generally users are satisfied with the quality of the data
However, quality is not necessarily consistent from one ground station to another
It is important that customised products are available from all ground stations
Will future processing allow for user defined products ?
OCTOBER 2000 IICWG-II Reykjavik, Iceland
SAR Data Format
Data should be delivered in a consistent format - independent of ground station
Data format inconsistencies will influence infrastructure at ice centers
More than one data format / compression could be supported
New formats for Radarsat-2 (GeoTiff ??)
OCTOBER 2000 IICWG-II Reykjavik, Iceland
SAR Data Continuity
It is evident that a gab between Radarsat-1 and 2 will have a strong impact on operations
Contingency plans are being prepared In general continuity is an important issue

The Role of IICWG
How do we proceed from here ?Establish a subgroup to
• Develop the principles and mechanisms for data access– Commercial SAR data– Other data sets (current and future), e.g. scatterometry data
• Influence flight agencies and data suppliers to accommodate the broader interests of the ice charting community
The challenge: designate points of contact, date and venue for this meeting before the end of IICWG-2
