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 1957-8. 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. Click to view graphic showing the sensors frequencies and optics involved in the Global Inter-agency IPY Polar Snapshot Year project.

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.

国际极年（IPY）是一项聚焦于北极和南极的协同研究活动。国际极年的历史始于1882年的首个为期一年的国际极年。自此，第二次国际极年于1932-1933年举行，而国际地球物理年则于1957-1958年举办。由国际科学理事会（ICSU）和世界气象组织（WMO）组织，第四次国际极年跨越了两年（2007-2009年），以强调极地研究的紧迫感。随着极地研究的持续进行，IPY认识到极地地区的变迁对全球具有影响。极地地区雪和冰的范围、厚度和持续时间的改变影响当地生态系统和渔业、农业等经济热点。全球数百万人的生命，尤其是生活在北极地区的人们，受到这些食物和水资源可用性以及北极污染的变化的影响。IPY 07-09专注于协同研究，并广泛探讨了北极与南极以及其他元素之间的复杂关系。超过60个国家和数千名研究人员参与其中，调查了200多个项目。议题包括北极与南极与地球物理元素、海洋和海冰、地球大气层、太空以及人类关系（新的IPY议题）之间的关系。协同研究的重点旨在为科学界建立国际、跨学科的合作基础，这一基础将在IPY 07-09结束后继续存在。合作研究伙伴关系将有助于极地研究克服障碍，取得进展，并允许科学家和全球社区共同理解极地地区变化的影响。

全球多机构IPY极地快照年（GIIPSY）ASF托管了名为全球多机构IPY极地快照年（GIIPSY）的IPY项目档案。GIIPSY的目标是在2007-2008年期间获取极地地区的高清卫星快照。主要目的是利用这些快照作为衡量过去和未来极地冰、海洋和陆地环境变化的基准。
