Eddy Flux Measurements, Pleistocene Park, Cherskii, Russia - 2009

In contribution to the Arctic Observing Network (AON), the researchers have established two observatories of landscape-level carbon, water and energy balances at Imnaviat Creek, Alaska and at Pleistocene Park near Cherskii, Russia. These will form part of a network of obervatories with Abisko (Sweden), Zackenburg (Greenland) and a location in the Canadian High Arctic which will provide further data points as part of the International Polar Year. This particular part of the project focuses on simultaneous measurements of carbon, water and energy fluxes of the terrestrial landscape at hourly, daily, seasonal and multi-year time scales. These are the major regulatory drivers of the Arctic climate system and form key linkages and feedbacks between the land surface, the atmosphere and the oceans. In support of these objectives, a new 32m tower was deployed in Pleistocene Park, about 20km south of NESS. This station is currently measuring fluxes of carbon dioxide, methane, water vapor and energy in addition to other meteorological variables.

为支持北极观测网络（Arctic Observing Network, AON）建设，研究人员分别在阿拉斯加州的伊姆纳维阿特溪（Imnaviat Creek）与俄罗斯切尔斯基（Cherskii）附近的更新世公园（Pleistocene Park）建立了两处针对景观尺度的碳、水与能量平衡观测站。上述站点将与瑞典阿比斯库（Abisko）站、格陵兰扎肯贝格（Zackenburg）站以及加拿大高北极地区的一处观测站点共同组成观测网络，作为国际极地年计划的组成部分，提供更多观测数据点位。本项目的该分支重点聚焦于在小时、日、季节及多年时间尺度下，对陆地景观的碳、水与能量通量开展同步观测。上述通量是北极气候系统的核心调控驱动因子，同时构成了陆面、大气与海洋之间关键的联结纽带与反馈机制。为支撑上述研究目标，研究团队在距NESS以南约20公里的更新世公园内架设了一座全新的32米观测塔。目前该站点除监测各类气象变量外，还可同步观测二氧化碳、甲烷、水汽及能量通量。
