Polar Environment Atmospheric Research Laboratory (PEARL)

北极仍然是地球上了解最少的环境之一，但它往往被视为气候变化许多方面的早期预警系统。还有臭氧层损耗和紫外线辐射以及空气质量变化的问题。 国际科学界一致认识到，迫切需要对北极的状况和过程进行直接观测和测量。许多国家都高度重视北极研究，最近的国际极地年努力就是这种关注的结果。加拿大在北极研究中有着特殊的利害关系，因为北极的大部分陆地都在加拿大境内。然而，在北极高地进行研究的机会非常有限，因为难以维持一个可行的研究地点。 该提案是为维持极地环境大气研究实验室（PEARL）所需的资金，该实验室位于加拿大尤里卡气象站气象服务处附近，距离北极仅1，100公里。世界上没有可比的网站。这个专门建造的实验室是独一无二的，因为它有“晴朗的天空”的夜晚，能够监测和获得冬季极地涡旋内外的测量数据，这是许多大气研究的重点。PEARL设施目前有40多名研究人员，包括本科生和研究生、加拿大大学和政府研究人员以及国际调查人员。 PEARL使加拿大研究人员能够在加拿大远北地区进行具有国际竞争力的科学和环境相关的大气研究。

The Arctic remains one of the Earth's least understood environments and yet it is often regarded as an early warning system for many aspects of climate change. There are also the issues of ozone depletion and ultraviolet radiation, and changes in air quality. The international scientific community unanimously recognizes the acute need for direct observation and measurement of conditions and processes in the Arctic. Many countries have assigned high priority to Arctic research and the recent International Polar Year (IPY) effort is a result of this concern. Canada has a particular stake in Arctic research because much of the Arctic land mass is within Canada. However, the opportunities for doing research in the high Arctic are very limited because of the difficulties of maintaining a viable research site. This proposal is for the funds necessary to maintain the Polar Environment Atmospheric Research Laboratory (PEARL) located at a site near the Meteorological Service of Canada's Eureka weather station and only 1,100km from the North Pole. There is no comparable site in the world. The purpose-built laboratory is unique in its "clear sky" nights and ability to monitor and obtain measurements from both inside and outside the winter polar vortex, the focus of much atmospheric research. More than 40 researchers including undergraduate and graduate students, Canadian university and government researchers and international investigators are currently involved in the PEARL facility. PEARL enables Canadian researchers to perform internationally-competitive as well as scientifically and environmentally relevant atmospheric research in Canada's far North.
