IASOA - Eureka Observatory

Eureka, Nunavut, Canada 80.050 N, 86.417 W, Ellesmere Island The Eureka station is composed of three sites: Polar Environment Atmospheric Research Laboratory (PEARL), Zero altitude Pearl Auxiliary Laboratory (0PAL), and Surface and Atmospheric Flux, Irradiance and Radiation Extension (SAFIRE). PEARL is situated on higher terrain in order to sample the atmosphere above the aerosol layer, from ground level to the middle and upper atmosphere, whereas 0PAL is closer to sea level in order to sample within the aerosol layer. SAFIRE is a tower instrumented for radiation and flux measurements. There are numerous instruments at Eureka, including, but not limited to, a radar and lidar for cloud studies, imagers, interferometers, photometers, radiation sensors, an ozone lidar, and standard weather measurements. Eureka is a testament to interagency and international cooperation among scientists. The principal agency in charge of Eureka is the CAnadian Network for the Detection of Atmospheric Change (CANDAC), which is a consortium of scientists from various Canadian universities. Detailed information about the station, associated agencies, instruments and principal investigators can be found at the CANDAC web site candac.ca/candac/index.php and at www.iasoa.org. Questions regarding station operations should be directed to Pierre Fogal ([e-mail]). Dr. James Drummond is the focal point for the science conducted at Eureka ([e-mail]).

加拿大努纳武特地区埃尔斯米尔岛尤里卡站，地理坐标为北纬80.050°、西经86.417°。该观测站由三个站点构成：极地环境大气研究实验室（Polar Environment Atmospheric Research Laboratory, PEARL）、零海拔极地辅助实验室（Zero altitude Pearl Auxiliary Laboratory, 0PAL）以及地表与大气通量、辐照度与辐射扩展站（Surface and Atmospheric Flux, Irradiance and Radiation Extension, SAFIRE）。PEARL选址于较高地势，以采集从地面至中高层大气的气溶胶层上方大气样本；0PAL则贴近海平面，用于采集气溶胶层内部的大气样本。SAFIRE为一座搭载辐射与通量测量仪器的观测塔。尤里卡站配备了丰富的观测仪器，涵盖但不限于用于云研究的雷达与激光雷达、成像仪、干涉仪、光度计、辐射传感器、臭氧激光雷达，以及常规气象观测设备。尤里卡站是跨机构与国际科学家协作的生动范例。主管该站的核心机构为加拿大大气变化检测网络（Canadian Network for the Detection of Atmospheric Change, CANDAC），该机构由加拿大多所高校的科研人员组成联盟。有关该观测站、关联机构、仪器及首席研究员的详细资料，可登录CANDAC官方网站candac.ca/candac/index.php与www.iasoa.org查阅。有关站点运营的咨询事宜，请联系Pierre Fogal（邮箱：[e-mail]）。James Drummond博士为尤里卡站科研工作的对接负责人（邮箱：[e-mail]）。
