International Polar Year 2007-2009
International Polar Year (IPY) was a collaborative research event focused on the Arctic and Antarctic. The history of IPY started in 1882 with the first year-long International Polar Year. Since then, a second IPY occurred in 1932-33 and an International Geophysical Year took place in 1957 -1958. The fourth IPY spanned two years (2007-2009) in order to emphasize a sense of urgency in polar research.

International Polar Year (IPY) was a collaborative research event focused on the Arctic and Antarctic. The history of IPY started in 1882 with the first year-long International Polar Year. Since then, a second IPY occurred in 1932-33 and an International Geophysical Year took place in 1957-8. Organized by the International Council for Science (ICSU) and the World Meteorological Organization (WMO), the fourth IPY spanned two years (2007-2009) in order to emphasize a sense of urgency in polar research. As polar research has continued, IPY has recognized that changes in polar areas have a global impact.
Changes in the extent, thickness and duration of snow and ice in polar regions affect local ecosystems and economic hot spots like fisheries and agricultural areas. Millions of lives around the globe, especially those living in the north, are affected by these changes in food and water availability and arctic pollution. IPY 07-09 focused on collaborative research and extensively explored the complex relationships between the Arctic and Antarctic and other elements. Over 60 countries and thousands of researchers participated, investigating more than 200 projects. Topics included Arctic and Antarctic relationships with geophysical elements, oceans and sea ice, Earth’s atmosphere, space, and human relations (a new IPY topic).
The focus on collaborative research was intended to build a foundation of international, interdisciplinary partnerships in the scientific community that would continue after IPY 07-09 ended. Cooperative research partnerships would aid polar research in making progress with fewer obstacles, and allow scientists and global communities alike to understand the effects of change in polar regions.
Global Inter-agency IPY Polar Snapshot Year (GIIPSY)
ASF hosts an archive of the IPY project titled the Global Inter-agency IPY Polar Snapshot Year (GIIPSY). GIIPSY’s objective was to obtain high-definition satellite snapshots of the polar regions during 2007-2008. The primary purpose is to use these snapshots as benchmarks for gauging past and future environmental changes in the polar ice, ocean, and land.
GIIPSY Missions Snapshot
In the spirit of IPY, GIIPSY scientists also seek to secure these datasets as our legacy to the next generations of polar scientists. GIIPSY comprises a group of polar scientists from around the world who have assembled a consolidated list of thematic objectives that call upon the collective resources of international and national space agencies. The programmatic goal is to identify ways in which the resources of space-faring countries can be used in such a way as to collect data with which to address these scientific objectives, without putting undo burden on any single organisation. To that end, GIIPSY seeks cooperation in terms of spaceborne instruments, data relay systems, ground segments, processing, and data archiving and distribution capabilities.

Space Task Group of the IPY Sub-Committee on Observations SAR Workshop (March 5-6, 2008)
Canadian Space Agency, St. Hubert, Canada
As part of ongoing IPY Space Task Group activities, the Canadian Space Agency hosted an IPY SAR/InSAR workshop in response to an action item from STG-1. The goal of the meeting was to develop an acquisition strategy for SAR and InSAR data that achieves the maximum number of IPY science objectives in such a way as to distribute the acquisition load across the different agencies – understanding that no single agency can accommodate all of the tasks. This will require a level of coordination between the space agencies that has not yet been attempted. The workshop focused on data acquisition requirements, as outlined by the scientific community, based on Agency strategic plans for IPY and unique capabilities of their systems. Data processing and distribution issues were briefly addressed but the primary objective was to populate the archive given the unique opportunity of IPY.
The workshop main tasks were:
1) To review existing GIIPSY science requirements as outlined in the Global Inter-agency IPY Polar Snapshot Year (GIISPY) Strategy Document.
2) To present the Agencies strategic priorities in line with IPY science activities.
3) To present and review SAR data which are being collected, and are planned for collection during the IPY.
4) To present the satellite and ground segment operators system capabilities and constraints related to the acquisition of data in support to IPY.
5) To attempt to forge a coordinated / multi-agency SAR acquisition plan for the remainder of IPY acquisitions.
In order to meet these ambitious objectives, invited attendees, which include members of the science and operational communities, space agencies operating SAR satellite; space agencies with data transmission, ground segment and processing capabilities, and ground segment operators, were requested to actively contribute to the achievement of the workshop objectives.

Summary Material
Space Task Group of the IPY Sub-Committee on Observations SAR Workshop (September 30 – October 1, 2008)
DLR, Oberpfaffenhofen, Germany
As a follow up to the STG action to enhance the coordination among the SAR Space Agencies in response to the IPY scientific objectives, a SAR/InSAR coordination workshop was held on 5/6 March 2008 at the Canadian Space Agency. As a result of this meeting, the SAR operating Agencies agreed on the strategic guidelines for imaging activities and for thematic priorities as outlined by the science community. Despite the significant way forward and considerable efforts we are putting to fulfill our commitments, there is still a need to develop a SAR Acquisition Consolidated Plan and discuss the way forward for a SAR processing strategy and data dissemination plan.
As part of the SAR coordination process, the German Aerospace Center (DLR) is organising a second meeting to address the harmonisation and coordination of the acquisition plans. The objectives of this meeting are:
* Consolidate the current SAR planning and imaging activities occurring under the auspices of IPY/STG in order to avoid gaps and overlaps and optimize resources (i.e. thematic / instrument matrix, common planning tool, etc.)
* Distribute imaging load according to Agencies’ capacities and priorities, and develop acquisition plans
* Look at a short/med/long term planning approach to continue the acquisitions (if at all possible)
The meeting will be held at the DLR facilities in Oberpfaffenhofen (Germany).
We now established the date of the workshop on 30 Sept./1 Oct.2008.

The International Council for Science (ICSU) and the World Meteorological Organization (WMO) approved the Global Interagency IPY Polar Snapshot Year (GIIPSY) as an 2007-2008 IPY project (Project #91). High-definition satellite snapshots of the Arctic and Antarctic would be invaluable polar documentation for comparing with past and future datasets. Therefore, GIIPSY worked to establish an international network of organizations willing to collaborate with their spaceborne satellites and share data processing, archiving, and distributing responsibilities. The IPY Space Task Group (STG) served as an intermediary between GIIPSY and international space agencies. GIIPSY was able to reach its goals by working with eight national space agencies and their spaceborne satellites.

IPY Data Archive
ASF was tasked with making its rich archive of imagery from the polar regions available to the science community for IPY. Satellite images over these remote regions allow researchers to make observations without facing extreme temperatures and with great cost savings.
Data were made available through a collaborative effort between the Canadian Space Agency (CSA), NASA, and the University of Alaska Fairbanks (UAF). Funding was provided from both UAF and NASA for the project. ASF’s goal is to continue to make these data available to a new generation of researchers interested in studying the Arctic or Antarctic.
