Arctic Science Archive Processing Project (ASAP)

Background• Radarsat-1

•Ideal EO system to monitor polar regions

•Still operational (2008-2009)

• Data continuity

•Radarsat-2 (Canadian government data allocation - $450M)

•Radarsat C (High revisiting frequency – 3 satellites)

• CSA submitted a proposal to the Canadian IPY office to support the coordination, acquisition, processing and dissemination of Radarsat data during the IPY period

• Large Radarsat-1 Archive collected over both polar regions (>250,000 images over the Arctic)

• CSA initiated the processing of a significant portion of the Radarsat-1 Canadian Archive - ASAP project ($1.5M)

ASAP Project

• National consultation (Nov-06)

• Three phases under which more than 7 500 Radarsat-1 archive data will be processed:

Phase 1 (50%): Blanket coverage in Fine 1 of the Canadian polar region and the Arctic Archipelago (2000-2001)

Phase 2 (25%): Seasonal polar snapshots between 2003 and now

Phase 3 (25%): Processing of images under specific areas of interests identified and agreed upon as supersites by the research communities

• Web Portal for images and products dissemination

Phase 1

Phase 2

Circumpolar ScanSAR Seasonal Coverage

Summer 2003 Fall 2003

Phase 2Circumpolar ScanSAR Seasonal Coverage

Winter 2004 Spring 2004

Phase 3

Next Steps …

• National consultation (supersites)

• Looking for the collaboration of other Agencies to complement the ASAP project

• ASAP Portal:

• Integration of two existing ScanSar mosaics of Canada (Winter and Summer mosaic)

• Integration of the Canadian Ice Service Radarsat-1 Archive data ( > 30,000 images)

• ASAP data & products will be accessible to IPY researchers

• Participate in the ICSU-WMO IPY Space Task Group
