Title:Fuji Hokuroku Flux Monitoring Data富士北麓フラックス観測データ
Identifier:JaLTER_Fujihokuroku.3.5
Abstract:
Center for Global Environmental Research, National Institute for Environmental Studies is conducting comprehensive monitoring of carbon cycle in terrestrial ecosystems under the program of Global Environmental Monitoring, which covers a wide range of environmental fields such as the atmosphere, ocean and biosphere. The Fujihokuroku (FHK) site is located in a forest at the foothills of Mt Fuji in Yamanashi Prefecture at an elevation of 1100 m. The long-term carbon cycle monitoring started in 2006 including the carbon dioxide exchange between the forest and the atmosphere as well as the carbon cycle processes in the ecosystem. Further information can be found at (http://db.cger.nies.go.jp/gem/moni-e/warm/flux/1forest/data_index.html). 国立環境研究所地球環境研究センターでは、大気・海洋・生物圏を含む地球環境モニタリングの一環として、陸域生態系の炭素収支に関する総合的なモニタリングを行っています。山梨県の富士山麓(標高約1100m)に位置する富士北麓(FHK)サイトでは、森林と大気の二酸化炭素交換量をはじめ、森林の炭素循環の各プロセスに関する長期モニタリングを2006から実施しています。詳細は(http://db.cger.nies.go.jp/gem/warm/flux/1forest/data_index.html)をご覧ください。
