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°。该尤里卡站包含三个观测站点：极地环境大气研究实验室（Polar Environment Atmospheric Research Laboratory，PEARL）、零海拔珀尔辅助实验室（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设于较高地势，用于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设备的观测塔。尤里卡站搭载了大量观测设备，包括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，以及常规气象测量仪器。尤里卡站是跨机构与国际科研合作的典范。负责尤里卡站的主管机构为加拿大大气变化探测网络（Canadian Network for the Detection of Atmospheric Change，CANDAC），该机构由来自加拿大多所高校的科研人员组成。有关该站点、合作机构、观测设备及首席研究员的详细信息，可访问CANDAC官网candac.ca/candac/index.php与www.iasoa.org查询。有关站点运行的相关问题，请联系Pierre Fogal（邮箱：[e-mail]）；负责尤里卡站科研工作的对接人为James Drummond博士（邮箱：[e-mail]）。
