Plant % cover by functional type for the ITEX CO2 flux survey plots at Toolik, Alaska; Abisko, Sweden; Svalbard, Norway; Zackenberg, Northeast Greenland; Anaktuvuk River Burn, Alaska and Barrow, Alaska 2003-2009.

Estimated aerial plant % cover by functional type in flux plots measured during the ITEX cirumarctic flux survey 2004-2006. Survey plots were located in the Toolik Lake LTER fertilization experiment in Alaska; at Imnavait Creek, Alaska; at Paddus, Latnjajaure and the Stepps site near Abisko in northern Sweden; at various sites in Adventdalen, Svalbard; in the Zackenberg valley, Northeast Greenland; at BEO near Barrow, Alaska and at the Anaktuvuk River Burn in Alaska. Measurements were made during the growing seasons 2003 to 2009.

本数据集收录了2004-2006年ITEX环北极通量调查期间，于通量观测样地内测定的、按功能型划分的植被盖度百分比估算值。调查样地分布于：阿拉斯加图利克湖长期生态研究（Long-Term Ecological Research, LTER）施肥实验样地、阿拉斯加Imnavait Creek样地、瑞典北部阿比斯库附近的Paddus、Latnjajaure及Stepps样地、斯瓦尔巴群岛Adventdalen的多处样地、格陵兰东北部Zackenberg山谷样地、阿拉斯加Barrow附近的BEO样地，以及阿拉斯加Anaktuvuk河火烧迹地样地。相关测定工作于2003至2009年的生长季内开展。
